Answer: The forces acting on both of them will increase in magnitude.
Explanation:
According to Coulomb's law, the electrostatic force between two bodies is proportional to the product of their two charges. If the charge on A is increased this product increases in size (it must have been non-zero to begin with, since there was a force between them at first). Thus, the force between them rises.
Answer:304 not 261
Explanation:
That is, in prototype form anyway – the custom Chiron Longtail hit 304 mph (490 km/h) last year, but the production version dubbed the Chiron Super Sport 300+ will be electronically limited to only 273 mph (440 km/h).

Answer:
No change in the specific heat.
Explanation:
Specific heat is an intrinsic property that it has not depend upon on the amount of substance or energy added, it depends upon the material.
So, when twice the amount of energy is transferred, specific heat of the material does not change rather the energy that is twice in the amount to 1 kg of that material cause it to warm 2.0° C.
B. Brittle Star is an echinoderm that moves by waving its arms.
Brittle star is a spiny, hard-skinned, long-armed animal, related to sea star, that lives on rocky sea floor, from shallow areas to the deepest areas. It uses its flexible arms for locomotion.
In order to change from 45 m/s up to 9 m/s down, the velocity
of the ball has to change by (45+9)= 54 m/s downward.
Gravity adds 9.8 m/s of downward speed to any falling object
every second.
So the change takes (54/9.8) = 5.5 seconds .
