Answer:
A
Explanation:
the nucleus is the center of the atom who controls the element.
Answer:
The temperature must the ring be heated so that the sphere can just slip through is 106.165 °C.
Explanation:
For brass:
Radius = 1.3590 cm
Initial temperature = 23.0 °C
The sphere of radius 1.3611 cm must have to slip through the brass. Thus, on heating the brass must have to attain radius of 1.3611 cm
So,
Δ r = 1.3611 cm - 1.3590 cm = 0.0021 cm
<u>The linear thermal expansion coefficient of a metal is the ratio of the change in the length per 1 degree temperature to its length.</u>
<u>Thermal expansion for brass = 19×10⁻⁶ °C⁻¹</u>
Thus,
Also,
So,
Solving for final temperature as:
<u>Final temperature = 106.165 °C</u>

The velocity of the satellite will be 200 kmph.
Since the satellite is in deep space, and there is nothing to restrict the motion of the satellite (No atmosphere or no friction), therefore the stopping of engine will not affect the velocity of the satellite.
Therefore the velocity of the satellite after few minutes will be 200 kmph.
