The translational speed of the bowling ball is 6.28 m/s.

Translational speed refers to the motion of an object in a straight line. It is the speed at which an object moves from one point to another in space. In the context of a ball rolling down an incline, translational speed would refer to the speed of the ball at any given moment as it moves in a straight line down the incline.

To find the translational speed of the bowling ball after it has rolled to the bottom of the incline, we need to use the equation of motion:

[tex]v = sqrt(v0^2 + 2ax)[/tex]

where v is the final velocity, v0 is the initial velocity (0 in this case), a is the acceleration (9.81 m/s^2), and x is the distance traveled (2 m).

So,

[tex]v = sqrt(0 + 2 * 9.81 * 2)\\v = sqrt(39.24)\\v = 6.28 m/s[/tex]

The bowling ball requires more force to roll than the basketball. This is because the bowling ball has more mass than the basketball, and therefore more resistance to motion.

Force is related to mass because the force required to move an object is proportional to its mass. This relationship is described by Newton's second law of motion, which states that the acceleration of an object is directly proportional to the force applied and inversely proportional to its mass. In mathematical form, this relationship is expressed as:

F = ma

The amount of force required to move an object is proportional to its mass and its velocity. Since the bowling ball has more mass, it requires more force to be applied in order to get it moving, and to keep it moving at a constant velocity. Additionally, because the bowling ball is inside a white box, its rolling friction is higher, further increasing the amount of force required to move it.

The number of photoelectrons that can be removed from a golden spoon is (30W / c) / (e x 5.1 eV). The amount to start from the same spoon is (42W) / (e x 5.1 eV).

The work function of a material is the minimum amount of energy required to remove an electron from the material.

a) To find the number of photoelectrons removed from the spoon, find the energy deposited in the spoon during 1 second. With 600W of consumption, the spoon receives 5% of this energy, which is 0.05 x 600W = 30W.

To convert this to energy per second, we need to divide by the speed of light, c: E = 30W / c. To convert this energy to electron volts, divide by the charge of an electron, e: E_ev = E / e. Finally, to find the number of electrons removed, divide this energy by the work function of gold, 5.1 eV: n = E_ev / (5.1 eV) = (30W / c) / (e x 5.1 eV),

b) To find the number of photoelectrons removed from the spoon with the industrial laser, find the energy deposited in the spoon during 1 second. With 42W of laser power, the energy deposited in the spoon during 1 second is 42W. To convert this to electron volts, divide by the charge of an electron, e: E_ev = 42W / e. Finally, to find the number of electrons removed, divide this energy by the work function of gold, 5.1 eV: n = E_ev / (5.1 eV) = (42W) / (e x 5.1 eV)

Answer: We can use Newton's second law, which states that the net force acting on an object is equal to its mass multiplied by acceleration.

Let's call the acceleration of the system "a". Then the net force acting on m1 is T1 - T2 + m1 * a = 0.

The net force acting on m2 is T2 - m2 * a = 0.

And the net force acting on m3 is T2 + m3 * a = 0.

Solving these three equations, we get:

T1 = T2 + m2 * a = 60.0 N + 8.00 kg * a

m1 * a = -T2 + 60.0 N + m1 * a

m3 * a = T2 - 60.0 N + m3 * a

Substituting T2 = 60.0 N, we get:

T1 = 60.0 N + 8.00 kg * a

m1 * a = -60.0 N + 10.0 kg * a

m3 * a = 60.0 N + 12.0 kg * a

Solving for the acceleration, we get:

a = (60.0 N + 8.00 kg * a) / (10.0 kg - 8.00 kg) = (60.0 N + 8.00 kg * a) / 2.0 kg

a = (60.0 N + 8.00 kg * a) / 2.0 kg = (60.0 N) / 2.0 kg + (8.00 kg * a) / 2.0 kg

a * 2.0 kg = 60.0 N + 8.00 kg * a

a = 60.0 N / 2.0 kg + 8.00 kg * a / 2.0 kg

a * 2.0 kg - 8.00 kg * a = 60.0 N

a * 10.0 kg = 60.0 N + 8.00 kg * a

a = 60.0 N / 10.0 kg = 6.0 m/s²

Finally, we can use T1 = 60.0 N + 8.00 kg * a to find T1:

T1 = 60.0 N + 8.00 kg * 6.0 m/s² = 60.0 N + 48.0 N = 108.0 N

So the acceleration of the masses is 6.0 m/s², and the tension T1 is 108.0 N.

Answer:

Explanation:

To solve for the mass of the football player, we can use the conservation of momentum principle, which states that the total momentum before a collision is equal to the total momentum after the collision. Assuming the collision is perfectly elastic, we have:

m1 * v1 + m2 * v2 = m1 * v1' + m2 * v2'

where m1 is the mass of the football player, v1 is the initial velocity of the football player, m2 is the mass of the referee, v2 is the initial velocity of the referee, v1' is the final velocity of the football player, and v2' is the final velocity of the referee.

Since the referee is at rest before the collision, we can set v2 = 0. Plugging in the given values, we get:

m1 * 8 + m2 * 0 = m1 * (-8) + m2 * 5

Expanding and solving for m1:

8m1 = -8m1 + 80

16m1 = 80

m1 = 5 kg

So, the mass of the football player is 5 kg.

Forces have both magnitude and direction and are measured in units of Newtons (N) in the SI system. Some common examples of forces include gravity, friction, tension, and electromagnetic forces.

Since the three forces are in equilibrium, their sum must be zero. Hence, we have:

The 12 N force is directed horizontally to the right, so the other two forces must sum to zero vertically. They can either both be directed upwards or both be directed downwards.

If both forces are directed upwards, then the sum of their magnitudes must equal -12 N vertically:

Explanation:

To find the final velocity and distance traveled during the acceleration, we can use the equations of motion:

v = u + at, where v is the final velocity, u is the initial velocity (30 m/s), a is the acceleration, and t is the time (6 s)

v = 30 m/s + a x 6 s

d = ut + 0.5at^2, where d is the distance traveled

d = 30 m/s x 6 s + 0.5 x a x (6 s)^2

Since acceleration (a) is not given, we can use one equation to solve for it and substitute into the other:

v = 30 m/s + a x 6 s

a = (v - 30 m/s) / 6 s

Substitute this into the second equation to find the distance:

d = 30 m/s x 6 s + 0.5 x (v - 30 m/s) / 6 s x (6 s)^2

So, we can find the final velocity and distance traveled once the acceleration (a) is known.

There will always be an electric field connected to an electric charge or a group of charges. Any charged object placed in this field will experience an electrostatic force as a result of how the field and the charge of the object interact. The force that would be felt by a positively charged particle if it were present at that precise location is represented by field lines.

Electric charges can move in response to a shifting magnetic field. Inducing electric currents in wires via this phenomenon is a typical practice in electric generators.

Answer:

Explanation:

To determine the velocity of the 35.0 kg car before the collision, we can use the principle of conservation of momentum. The total momentum of the system before the collision is equal to the total momentum after the collision.

Momentum before collision = Momentum after collision

m1v1 + m2v2 = (m1 + m2)vf

where:

m1 = 25.0 kg (mass of first car)

m2 = 35.0 kg (mass of second car)

v1 = velocity of first car before collision

v2 = velocity of second car before collision

vf = final velocity of the combined cars after collision

Since the first car slows down to 1.50 m/s to the right after the collision, and the second car moves 4.50 m/s to the right, we can write:

vf = (v1 + v2) / 2 = (1.50 + 4.50) / 2 = 3.00 m/s

Substituting the given values into the equation for conservation of momentum, we have:

25.0 kg x 5.00 m/s + m2 x v2 = 60.0 kg x 3.00 m/s

Solving for v2, the velocity of the second car before the collision, we get:

v2 = (60.0 kg x 3.00 m/s - 25.0 kg x 5.00 m/s) / 35.0 kg = 2.14 m/s

So the velocity of the 35.0 kg car before the collision was 2.14 m/s.
