Answer:
true
Explanation:
this the nucleus is located at the centre and contains protons and neutrons
It depends on the direction in which the shell is launched. The time can be anything from 3.6 seconds to never.
The object will not be able to accelerate perpendicular to direction of motion
Answer:
1)
Acceleration (a)=change in velocity/ change in time
Velocity (v)=90m/s
Time=0.0005s
a=90/0.0005
The acceleration =180000m/s^2 or 180km/s^2
Force = mass x acceleration
m=40g= 0.04kg
F= 0.04x 180000
F= 7200N or 7.2kN
