Answer:12.92 N, 17.98 N
Explanation:
Given
Speed of ball
mass of ball (m)=0.057 kg
time (t)=0.25 s
(a)Average Force(F)
=12.92 N
(b)Intial velocity(u)
Final velocity (v)
Average Force
F=17.984 N
Answer:32 m/s/s
Explanation: since F=M*A, F=16N, M=0.5kg, A= F/M
A=16/0.5
A=32 m/s/s
The cold air increases pressure on the basketball, causing it to appear flat. When it warms up that pressure is taken off, so the basketball is at it's normal state.
Answer:
Explanation:
The temperature in stratosphere is generally about 270 K
molecular weight of an ozone molecule = 48 gm/mole
now formula for most probable velocity
plugging the values we get
