Answer:
False.
Explanation:
Mass is the amount of matter in a given object. Weight is the force acting on an object due to gravity.
Answer:
he difference between X-rays and visible radiation is in the energy of each foton.
Explanation:
Visible light and X-rays are electromagnetism waves with the same origin betray the atomic, but the energy of transioin wings is different,
E = h (v_f - v₀)
With this equation we see that the energy is proportional to the difference between the atomic levels where the ranscion occurs, the X-rays the transition involves deep levels n = 1 or 2 for which the energy of the emitted photon is very high.
The visible radiation the transition is between levels closer so that the emitted light has a lower frequency and is in the range of the visibly
Consequently, the difference between X-rays and visible radiation is in the energy of each foton.

It is specified that the legal requirements for the braking system that:
A reasonable distance should be practiced in stopping your vehicle.
Adjournment from the jar or shudder should be smooth and free.
A good braking system’s other necessities are:
Unaffected by heat, water, road grit, dust etc.
Constant continued application while moving downwards from a hill should not decrease its effectiveness and it must have good anti fade characteristics
Adequate durability with economical maintenance and adjustment Its durability must be enough and must have proper adjustment and maintenance.
