Answer:

through a magnetic field.

Explanation:

Answer:

The answer is "52.61 ft/s"

Explanation:

Taking the motion in the z-direction is [tex]u_z = 32 , \ \ a_z = - 32[/tex]

[tex]t = 2 \frac{u_z}{( - a_z )}\\\\[/tex]

  [tex]= 2 \times \frac{32}{32}\\\\ = 2 \ sec\\\\[/tex]

z-axis change is zero z and the  x-path the same way:

[tex]= u_x t + \frac{1}{2} a_x t^2 \\\\= 40 \times 2 + 0.5 \times 0 \times 2^2 \\\\ = 40 \times 2 + 0.5 \times 0 \times 4 \\\\ = 80 +0\\\\= 80 \ ft \ \ i[/tex]

In y-direction:

[tex]= 0 \times t - \frac{1}{2} \times (6) \times 2^2\\\\ = - \frac{1}{2} \times (6) \times 4\\\\ = - (6) \times 2\\\\= - 12 ft \ \ j[/tex]

the ball lands at:[tex]( 80 i - 12 j + 0 k ) ft[/tex]  

Magnitude:

[tex]\to ( 80^2 + (-12)^2 )^{\frac{1}{2}}\\\\\to ( 6400 + 144 )^{\frac{1}{2}}\\\\\to ( 6544 )^{\frac{1}{2}}\\\\\to 80.89 \ ft[/tex]from the origin.

angle:

[tex]\to \tan^{-1} ( \frac{12}{80} )\\\\\to 8.53^{\circ}[/tex]

velocity:

[tex]\to 40 i + ( 0 - 6 \times 2 ) j + ( 32- 32 \times 2 ) k\\\\\to 40 i + ( - 12 ) j + ( 32- 64 ) k\\\\\to 40 i - 12 j - 32 k\\\\\to ( 40^2 + 12^2 + 32^2 )^{\frac{1}{2}}\\\\\to (1600+144+1024)^{\frac{1}{2}}\\\\\to 2768^{\frac{1}{2}}\\\\\to 52.61\ \ \frac{ft}{s}[/tex]

Answer:

a) 102 meters

b) 14 meters

c) The direction is eastward.

Explanation:

Distance is said to be the length between two points. It is a scalar quantity.

a) The distance moved = 36 + 44 + 22

                                       = 102 meters

b) Displacement is the distance moved in a specified direction.

Representing the distance moved with specific direction as a directed number, 36 meters eastward = +36, 44 meters westward = -44, and 22 meters eastward = +22

/Displacement/ = +36 -44 +22

                         = +58-44

                         = 14

The magnitude of the displacement is 14 meters.

c) The direction is eastward.

So that the magnitude of displacement and his direction is 14 meters eastward.

The human body is a Conductor

Answer:

a = 17.83 m/s²

Explanation:

Given:

Fnet = 345N - 24N

m = 18kg

Unknown:

a or Acceleration of the crate

Formula and solution:

Fnet = F1 + F2

Fnet = 345N - 24N

Fnet = 321N

a = Fnet/m

a = 321 kg m/s² ÷ 18 kg

Final Answer:

a = 17.83 m/s²

Answer:

fly apart

Explanation:

gravity holds everything in place by constantly attracting both of the objects

without gravity, the objects would not be attracted anymore. Hence, they fly apart.

Answer:

The net force exerted on the race-car driver is 727.3 N

Explanation:

Acceleration

According to Newton's second law of motion, the acceleration of an object a is directly proportional to the net force F and inversely proportional to the object's mass m:

[tex]F=m.a[/tex]

Since we don't have the value of the acceleration, we must use the kinematic equations to calculate it.

The main formula for accelerated motion is:

[tex]v_f=v_o+a.t[/tex]

Where vf is the final speed of the object, vo is its initial speed, a is the acceleration, and t is the time.

The race-car driver accelerates from vo=0 to 50 m/s in t=5.5 s. We can calculate the acceleration, solving the above equation for a:

[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]

[tex]\displaystyle a=\frac{50-0}{5.5}[/tex]

[tex]a=9.09\ m/s^2[/tex]

Now we calculate the net force:

[tex]F=80\ Kg\cdot 9.09\ m/s^2[/tex]

[tex]\boxed{F=727.3\ N}[/tex]

The net force exerted on the race-car driver is 727.3 N

Answer:

-9.8m/s^2 x 2.2 = -21.56m/s^2 50m/s - 21.56m/s^2 = 28.44m/s

Answer:

The atomic particles given off as a result of nuclear fission are alpha and beta.

Explanation:

Answer:

C

Explanation:

Given that a 2455 kg car was pushed by 77 kg student with a force of 720 N.

According to Newton's third law of motion which state that in every action, there will be equal and opposite reaction.

The action on the car = 720 N

The reaction from the car = - 720 N

Therefore, the force the car will apply on the student will be -720N.

The correct answer is C

Answer:

Explanation:

When many copies are made, the quality of digital copies

decreases, but not as much as that of analog copies.

When many copies are made, the quality of digital copies decreases, but not as much as that of analog copies. Option D is correct.

Digital data is information represented as a string of discrete symbols, each of which can take only one of a finite number of values from some alphabet

The primary aim of digital memory is to enable the storage and retrieval of binary data.

The benefits of digital storage of information over analog procedures are similar to the advantages of digital communication of information over analog communication.

Copies of stored digital data are better than copies of stored analog data. When many copies are made, the quality of digital copies decreases, but not as much as that of analog copies.

Hence option D is correct.

Answer:

The quantization of energy refers to the fact that at subatomic levels, energy is best thought of as occuring in discreet "packets" called photons. The red and blue photons are therefore "quantized" just as dollar bill denominations are "quantized". Each photon contains a unique amount of discreet energy.

Answer:

The maximum height above the ground the rocket reaches is 123.1 m.

Explanation:

Let's find the final velocity at a distance of 200 m:

[tex] v_{f}^{2} = v_{0}^{2} + 2ad [/tex]

Where:

[tex]v_{f}[/tex] is the final speed =?

v₀ is the initial speed =0

a is the acceleration = 1.25 m/s²

d is the distance = 200 m

[tex]v_{f} = \sqrt{2ad} = \sqrt{2*1.25 m/s{2}*200 m/s} = 22.4 m/s[/tex]    

Now, when the engines of the rocket turn off and it is subject only to gravity, the height reached is:

[tex] v_{fy}^{2} = v_{0y}^{2} - 2gh [/tex]

Where:

[tex]v_{f}[/tex] = 0

[tex]h = -\frac{v_{fy}^{2} - v_{0y}^{2}*sin(\theta)}{2g} = \frac{(22.4*sin(35))^{2}}{2*9.81 m/s^{2}} = 8.4 m[/tex]

Finally, the maximum height above the ground is:

[tex] h_{max} = h + H [/tex]

Where H is the vertical component of the 200.0 meters.

[tex]h_{max} = h + H = 8.4 m + 200.0 m*sin(35) = 123.1 m[/tex]

Therefore, the maximum height above the ground the rocket reaches is 123.1 m.

Answer:

D.

Explanation:

Answer:

ok sooooo,

F=MA

you are looking for a

you have F= 850 N and M= 85 kg

you divide the force with the mass

you get A= 10 m/s²

Answer:

Explanation:

Time during which there was acceleration = (v - u)  / a = 5 / 1.5 = 3.33 s

Time during which there was deceleration = (v - u)  / a = 5 / 2 = 2.5 s

Distance travelled during acceleration = 1 /2 a x t² = 1/2 x 1.5 x 3.33²

= 8.32 m

Distance travelled during deceleration = 1 /2 a x t² = 1/2 x 2 x 2.5²

= 6.25 m

Total distance travelled = 400 m

distance travelled when the velocity was uniform = 400 - ( 6.25 + 8.32 )

= 385.43 m

uniform velocity = 5 m /s

time  during uniform velocity existed

= 385.43 / 5 = 77.1 s

Total time required in the journey = 77.1 + 3.33 + 2.5

= 82.93 s

Answer:

A. The circuit's current drops. b. The circuit's resistance drops c. The voltage across it is zero d. The voltage remains the same.

Explanation:

a. What would happen to the circuit's current

Since the circuit is in series and one resistor is shorted, the current in the circuit would drop since it is a series circuit and one resistor has been shorted.

b. What would happen to the circuit's resistance

The resistance of the circuit drops by the value of the resistance shorted since it is a series circuit and the shorting cuts off this resistor from the circuit.

c. What would happen to the voltage across the shorted component

The voltage across the shorted component is zero because, since no current flows through it and we know that voltage V = IR and if I = 0, V = 0 × R = 0 V. So, the voltage across it is zero.

d. What would happen to the voltage across the other components

The voltage across the other components remains the same as the initial voltage because, the short transfers the current across the shorted component and makes the shorted component disappear from the circuit. The short thus makes it seem like the source voltage is directly connected to the other components across the shorted resistor. So, the new voltage across the other components is the initial voltage in the circuit before the short.

Answer:

A

Explanation:

Once the stone is thrown, with direction vectors and initial velocity will keep on traveling for infinite period unless there is another force to stop it.

For example, Newton's 1st law of Motion: ''Every inanimate body will continue its state of rest/motion unless acted upon by an external unbalanced force''

Since there is no friction, drag or any viscous force, our stone will travel for infinite period of time.
