The correct option is C.
When the temperature of an object that is giving off light is increased, the particles in the object will move at a faster rate and there will be increased vibration of these molecules. This will makes the object to emit more light and to shine more brightly. Thus, the higher the temperature, the brighter the light that will be emitted.
The force applied to the lever is 400 N, because the force applied by the lever (800 N) divided by the mechanical advantage of the lever (4) equals
400 N.
(800/4) = 200
It's Z.
Without any force acting on it an object travels in a straight line.
In order to bend away from a straight line the object needs a force acting on it.
In order to move along a circle, the force on the object points toward the center of the circle. It's called the centripetal force.
Since the object's direction is changing it has acceleration.
The acceleration points toward the center of the circle.
Answer:
a liquid is increased by 48.5 degrees Celsius, it expands by 0.0920 m^3. Explanation:
This question involves the concepts of the thin lens formula, focal length, and image distance.
The image of the house is "16 ft" away from the lens.
According to the thin lens formula:
where,
f = focal length = 8 ft
p = object distance = 16 ft
q = image distance = ?
Therefore,
<u>q = 16 ft</u>
