1.2ms-1
6.0ms-1
12.0ms-1
0.6ms-1
Correct answer is C
V = u - gt
u = v + gt
= 0 + 10 x 1.2
= 12ms−1
The total area under a force-velocity graph represents
energy
momentum
power
pressure
Correct answer is C
Power = Force x Velocity.
Therefore, the area under the force- velocity graph gives Power.
3.1ms-2
5.2ms-2
6.0ms-2
8.7ms-2
Correct answer is D
a = g sin θ
= 10 sin 60
= 8.7 ms−2
The slope of a linear distance-times graph represents
acceleration
displacement
speed
velocity
Correct answer is C
No explanation has been provided for this answer.
Solid friction, like viscosity is
independent of the surface area in contact
independent of the relative motion between layers
dependent on normal reaction
in opposition to motion
Correct answer is D
The force acting on a body due to the viscous resistance of the surrounding fluid is called the drag force and it acts in the direction opposite to the direction of motion. So also does friction.
