Light travels at a speed of 3.00 x 10^11 cm/s. What is the speed of light in kilometers/hour?
rewona [7]

As 1 km = 1000 m = 1000,00 cm,

So, 1 cm = (1/1000,00) km

1 hour = 60 × 60 s = 3600 s

So,  1 s = (1 / 3600) hour

The light travels at a speed of 3.00 \times 10^{11}  \ cm/s.

In kilometer/hour,

3.00 \times 10^{11}  \ cm/s = 3.00 \times 10^{11} \frac{(1/1000,00) km}{ (1 / 3600) hour} = 108 \times 10^8 \ km/hour

An electric lightbulb in a lamp fixture is illuminating a small room. The system consists of the lightbulb, the lamp fixture, th
mixas84 [53]

The role of thermal energy is to balance the electrical energy lost from the light bulb.

<h3>Energy conservation</h3>

The law of energy conservation states that energy can neither be created nor destroyed but can be transformed from one form to another.

<h3>Thermal energy</h3>

This is a form of energy that occurs due to rise in temperature.

The role of thermal energy is to balance the electrical energy lost from the light bulb.

A massless spring with force constant ????=200N/m hangs from the ceiling. A 2.0-kg block is attached to the free end of the spri
Makovka662 [10]

Answer:

-0.4454 Joules

Explanation:

m = Mass of block = 2 kg

h = Height of extension = 17 cm = x

g = Acceleration due to gravity = 9.81 m/s²

Potential energy of the spring

P=mgh\\\Rightarrow P=2\times 9.81\times 0.17\\\Rightarrow P=3.3354\ J

The kinetic energy of the spring

K=\frac{1}{2}mx^2\\\Rightarrow K=\frac{1}{2}\times 200\times 0.17^2\\\Rightarrow K=2.89\ J

In this system as the potential and kinetic energy is conserved from work energy equivalence we get

W=P-K\\\Rightarrow W=2.89-3.3354\\\Rightarrow W=-0.4454\ J

The work done by friction is -0.4454 Joules

A parent pushes a balanced frictionless playground merry-go-round. The parent exerts a force F tangent to the merry-go-round res
Alexandra [31]

Answer:

F = 150 N

Explanation:

Torque being applied by parent

= F  x r

where F is force applied tangentially and r is point of application of force from axis of rotation ( center )

given torque = 240 Nm

r = 1.6 m

F x r = 240

F x 1.6 = 240

F = 150 N

So a force of 150 N is applied by the parent to achieve the given torque.

This force will also be applied by the merry - go- around  on the parent as reaction force according to Newton's third law. The parent will not be pushed back by this force  because he is standing on a rough surface . Friction of surface will help him remain stationary on the ground.
