A=(vf-vi)/t
a=(50-25)/10
a=2.5m/s^2
Answer:
dear can you provide the circuit of the robot
Answer:
Here, force=20N and displacement=10m
Work=Force×Displacement=20N×10m=200Nm
Answer:
Explanation:
a ) The velocity will never be zero . The velocity will be minimum at the highest point of projectile, which will be equal to the horizontal component of the initial velocity.
b ) The velocity will be minimum when its kinetic energy will be minimum . Kinetic energy will be minimum when its potential energy will be maximum.
Its potential energy will be maximum at the highest point so velocity will be minimum at the highest point.
c ) Velocity will never be the same as initial velocity because constant force of gravitation is acting on the projectile all the time.
d ) At the moment when the projectile returns back and hits the ground, the speed becomes equal to the initial speed ( at t = 0 ) because its kinetic energy becomes the same as initial energy , the height becoming zero.
Explanation:
- effect of density in speed of sound.
- effect of direction of wind in speed of sound.
because there is no medium to travel sound in vacuum.
hope it helps.
