'Acceleration' means any change in speed or direction
of motion.

Answer:

C. A person running 100 m straight across a field at a constant speed.

Explanation:

Acceleration is defined as the change in the velocity per unit time. Velocity have both direction and magnitude (speed) . <u>So, acceleration involves both change in direction and speed.</u>

A).  The satellite is in a curved orbit, so direction of satellite is constantly changing. Hence, not the answer.

B). The car is following a curve, so its direction is changing. Hence, not the answer.

<u>C). The person is running straight at constant speed which means no change of speed or direction. Hence, it is the answer.</u>

D). The person is on curved track, so his/her direction is changing. Hence, not the answer.

if ionization energy us high than force of attraction Is high so it is not easy to remove and vice versa .

When the pressure that a gas exerts on a sealed container changes from 1100 bar to 75.5 bar, the temperature changes from k to 2
Serjik [45]
Gay-Lussac's law gives the relationship between pressure and temperature of gas. For a fixed amount of gas, pressure is directly proportional to temperature at constant volume.
P/T = k
where P - pressure , T - temperature and k - constant
\frac{P1}{T1} =  \frac{P2}{T2}
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
substituting the values in the equation 
\frac{1100 bar}{T}  =  \frac{75.5 bar}{298 K}
T = 4342 K
initial temperature was 4342 K
