Develop a logical argument as to why television satellites, which broadcast information as electromagnetic radiation, can send signals from the vacuum of space?
The correct answer to this open question is the following.
Although you did not include options for this question, we can say the following.
Trying to be clear and concise, television satellites, which broadcast information as electromagnetic radiation, can send signals from the vacuum of space because electronic radiation can travel throughout space with no medium that transports it. Electronic radiation needs no material channel or medium to travel such as wires or cable.
That is how technology has developed wonders such as satellite communications for telephone, TV, or the internet. Information, data, sound, and images travel through transverse waves that easily move through the vacuum of space.
Electromagnetic radiations are defined as waves that do not require a medium for propagation. The EM waves have electric and magnetic vectors that do not require any medium to propagate.
The arguments can be explained as:
The Television antennae receive the signals in the form of electromagnetic waves.
The waves are transmitted from the satellites present in space. These waves are then transmitted to the TV station, where the information is then broadcasted. Other electronic devices such as cellular phones, computers, and FM radios have been developed using the propagation of the EM waves.
Thus, the EM waves do not require propagation due to which the signals can be easily transmitted from space.

Which types of rocks can become metamorphic rock?
A. clastic sedimentary rock
B. both igneous and sedimentary rock
C. clastic or chemical sedimentary rock
D. both igneous and metamorphic rock
Answer:
i think the answer could be both B. and D. bc any type of rock can become a metamorphic rock with right conditions
Explanation:
A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock. Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock.
Answer:
B.) Both Igneous and Sedimentary rock
Explanation:
Since Metamorphic rocks can form from either Igneous or Sedimentary rocks. Since the sedimentary particles from which sedimentary rock is formed can be derived from a metamorphic, igneous, or another sedimentary rock, all three rock types can be melted to form magma.
A Penny is dropped and falls freely from the top of the Empire State building 443m high. What information do you know? 1b. How long does it take to hit the ground? 1c. How fast is it moving right before it hits the ground?
Answer:
1b. 9.51 s
1c. 93.18 m/s.
Explanation:
1a. From the question given above, the following data were obtained:
Initial velocity (u) = 0 m/s
Height (h) = 443 m
Acceleration due to gravity (g) = 9.8 m/s²
1b. Determination of the time it takes for the penny to get to the ground.
Height (h) = 443 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =?
h = ½gt²
443 = ½ × 9.8 × t²
443 = 4.9 × t²
Divide both side by 4.9
t² = 443/4.9
Take the square root of both side
t = √(443/4.9)
t = 9.51 s
1c. Determination of the speed of the penny before it hits the ground.
Initial velocity (u) = 0 m/s
Height (h) = 443 m
Acceleration due to gravity (g) = 9.8 m/s²
Final velocity (v) =.?
v² = u² + 2gh
v² = 0² + 2 × 9.8 × 443
v² = 0 + 8682.8
v² = 8682.8
Take the square root of both side
v = √8682.8
v = 93.18 m/s

Add the following vectors together:
35 km at 25 degrees N of E
15 km at 10 degrees E of N
Answer:
The resultant vector is 45.3 N 40.74° North of East
Explanation:
The given vectors can be presented as follows;
35 km at 25 degrees N of E = 35 × cos(25)·[tex]\mathbf{\hat i}[/tex] + 35 × sin(25)·[tex]\mathbf{\hat j}[/tex]
15 km at 10 degrees E of N = 15 × cos(90 - 10)·[tex]\mathbf{\hat i}[/tex] + 15 × sin(90 - 10)·[tex]\mathbf{\hat j}[/tex]
15 km at 10 degrees E of N = 15 × cos(80)·[tex]\mathbf{\hat i}[/tex] + 15 × sin(80)·[tex]\mathbf{\hat j}[/tex]
The sum of the vectors becomes;
∑d = 35 × cos(25)·[tex]\mathbf{\hat i}[/tex] + 15 × cos(80)·[tex]\mathbf{\hat i}[/tex] + 35 × sin(25)·[tex]\mathbf{\hat j}[/tex] + 15 × sin(80)·[tex]\mathbf{\hat j}[/tex]
∑d ≈ 34.33·[tex]\mathbf{\hat i}[/tex] + 29.56·[tex]\mathbf{\hat j}[/tex]
The magnitude of the resultant vector = √(34.33² + 29.56²) ≈ 45.3 N
The direction = tan⁻¹(29.56/34.33) ≈ 40.74° North of East
The resultant vector = 45.3 N 40.74° North of East

17. At what speed must an object be launched vertically upward for the
object to reach a maximum height of 16 meters above its starting position.
(Do not include units, do not include a sign, use 3 sig figs) *
===============================================
Explanation:
When starting at a height of 0, and initial velocity v, the equation of projectile motion is
y = -4.9x^2 + v*x
Where x is the time in seconds and y is the height at time x.
The vertex (h,k) of this parabola is the highest point. In general the vertex has its x coordinate at h = -b/(2a), so,
h = -b/(2a)
h = -v/(2*(-4.9))
h = v/(9.8)
Plug this into the first equation shown above. Also, plug in y = 16. Solve for v.
So we get the following.
y = -4.9x^2 + v*x
16 = -4.9(v/9.8)^2 + v*(v/9.8)
16 = (-5/98)v^2 + (5/49)v^2
16 = (-5/98)v^2 + (10/98)v^2
16 = (-5/98+10/98)v^2
16 = (5/98)v^2
(5/98)v^2 = 16
v^2 = 16*(98/5)
v^2 = 313.6
v = sqrt(313.6)
v = 17.708754896943
v = 17.7
The starting velocity must be roughly 17.7 meters per second.

Answer:
The value of the charge is 6 c. Option c.
Explanation:
Electric Field
The electric field is defined as the force per unit charge that would experience a small positive test charge if held at some point in space.
The force F on a charge q at any point in space is equal to the product of the charge and the electric field E at that point .
[tex]F=q\cdot E[/tex]
Since we know the value of the electric field E=6\ N/c and the force F=36 N experienced by a certain charge q, we can solve the above equation for q:
[tex]\displaystyle q=\frac{F}{E}[/tex]
[tex]\displaystyle q=\frac{36\ N}{6\ N/c}[/tex]
q=6 c
The value of the charge is 6 c. Option c.
This 90 kg anvil is about to fall from a 0.9 m high bench. What is its PE?
Use g = 9.8 m/s2 for the acceleration due to gravity.
Answer:
Option D. 793.8 J
Explanation:
From the question given above, the following data were obtained:
Mass (m) of object = 90 Kg
Height (h) = 0.9 m
Acceleration due to gravity (g) = 9.8 m/s²
Potential energy (PE) =...?
Potential energy is simply defined as the energy possessed by an object by reason of its position. Mathematically, it can be expressed as:
PE = mgh
Where:
'PE' is the potential energy.
'm' is the mass of object.
'g' is the acceleration due to gravity.
'h' is the height to which the object is located.
With the above formula, we can obtain the potential energy, PE as follow:
Mass (m) of object = 90 Kg
Height (h) = 0.9 m
Acceleration due to gravity (g) = 9.8 m/s²
Potential energy (PE) =...?
PE = mgh
PE = 90 × 9.8 × 0.9
PE = 793.8 J
Therefore, the potential energy of the object is 793.8 J

Newton throws an apple straight up at 10 m/s. What is the ball's velocity
after 1.4 seconds?
Answer:
23.72m/s
Explanation:
The final velocity can be calculated using the formula:
V = u + at
Where; v = final velocity (m/s)
u = initial velocity (m/s)
a = acceleration due to gravity (m/s²)
t = time (s)
Based on the provided information, u = 10m/s, t = 1.4s, a = 9.8m/s²
V = 10 + (9.8 × 1.4)
V = 10 + 13.72
V = 23.72m/s

An object that is launched from the top of the tower is dense enough that air resistance can be ignored. The object's initial velocity has components (vx = 30 m/s, vy = 20 m/s). What are the components of the object's velocity 3 seconds after launch?
Answer:
The components of the object's velocity 3 seconds after launch are
[tex]v_x = 30[/tex] m/s and [tex]v_y=-9.43[/tex] m/s.
Explanation:
The given components of initial velocity are
[tex]v_x= 30[/tex] m/s,
[tex]v_y= 20[/tex] m/s.
Assuming the y-axis is along the direction of gravitational force, so, the velocity along the x-axis will remain unchanged.
So, the x-componebt of the velocity after 3 seconds, [tex]v_x = 30[/tex] m/s.
Using the equation of motion along the y-direction, the final velocity, v, of a mass after time, t, having initial velocity, u is
v=u+at
In this case, [tex]u=y_y= 20 m/s, a=-9.81 m/s^2[/tex] ( as upward direction is taken as positive)
So, at time, t=3s, the final velocity in y-direction is
[tex]v= 20+(-9.81)\times 3[/tex]
[tex]\Rightarrow v=20-29.43[/tex]
[tex]\Rightarrow v= -9.43 m/s[/tex]
So, the y-component of the final velocity is 9.43 m/s in the downward direction.
Hence, the components of the object's velocity 3 seconds after launch are
[tex]v_x = 30 m/s[/tex] and [tex]v_y=-9.43 m/s[/tex].
The final vertical velocity of the object after 3 seconds is 49.4 m/s.
The final horizontal velocity of the object is 30 m/s.
The given parameters;
initial horizontal velocity, Vx = 30 m/sinitial vertical velocity, Vy = 20 m/stime of motion, t = 3 sThe final vertical velocity of the object after 3 seconds is calculated as follows;
[tex]v_f_y = v_0_y + gt\\\\v_f_y = 20 + 3(9.8)\\\\v_f_y = 49.4 \ m/s[/tex]
The final horizontal velocity of the object is the same as the initial horizontal velocity because horizontal motion is not affected by gravity.
[tex]v_f_x = v_0_x = 30 \ m/s[/tex]

Two workers are sliding 270 kg k g crate across the floor. One worker pushes forward on the crate with a force of 430 N N while the other pulls in the same direction with a force of 230 N N using a rope connected to the crate. Both forces are horizontal, and the crate slides with a constant speed. What is the crate's coefficient of kinetic friction on the floor?
Answer:
The value is [tex]\mu_ k = 0.249[/tex]
Explanation:
From the question we are told that
The mass of the crate is [tex]m = 270 \ kg[/tex]
The force applied by the first worker is [tex]F_1 = 430 \ N[/tex]
The force applied by the second worker is [tex]F_2 = 230 \ N[/tex]
Generally the kinetic frictional force between the crate and the floor is equal to the force applied by both worker , this is mathematically represented as
[tex]F_f = F_1 + F_2[/tex]
Here [tex]F_f[/tex] is the frictional force and this is mathematically represented as
[tex]F_f = \mu_ k * m * g[/tex]
So
[tex]\mu_ k * m * g = F_1 + F_2[/tex]
=> [tex]\mu_ k * 270 * 9.8 = 430 + 230[/tex]
=> [tex]\mu_ k = 0.249[/tex]
