When she lines up------1st law: the ball will be at rest until she acts on the ball

The first law state that "In the first law, an object will not change its motion unless a force acts on it."

When she kicks the ball----2nd law: the ball constantly changes direction and velocity depending on the applied force by her

The second law states that "In the second law, the force on an object is equal to its mass times its acceleration."

When she scores a goal-----3rd law: the force with which she kicks the ball to score a goal is equal to the reaction of the goal net

The third laws states that "In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction."

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:

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.

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

Explanation:

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.

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]

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:

letter D.

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:

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.

I hope this helps :)

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
