Using the following mathematical relations that represent two physical quantities:
Quantity (A)= 1 /2 Xmass X velocity squared k.E=1/2mv2 Quantity (B)=Force x Displacement. (W = F. d) So that, the dimensional formula (ML2 T -2 ) represents :
Quantity (A) only
Quantity (B) only
Both (A & B )
Neither (A) nor (B)
A horse tries to pull a wagon loaded with wood. If the pull force of the horse represents an "action", which force of the following represents the "reaction"?
A The friction force between the wagon wheels and the ground.
The pull force of the wagon to the horse.
The air resistance to the wagon.
The friction force between the horse legs and the ground
A stone and a ball are projected upwards at the same time, where the stone is projected at 20m/s while the ball at 10m/s. If the maximum height reached by the ball is (H), What is the maximum height reached by the stone? (neglecting air resistance against the movement of stone and ball)
½ H
H
2H
4H
The figure represents a ball falling freely from a height (H) above the ground. It takes 2s to reach midway to ground ( H). What is the required time for the ball to cover the other half distance to the ground? Given that: (g = 10 m/s2 )
3 s
2 s
0.83 s
0.5 s
A projectile is projected from a canon by 45o with the horizontal to reach a maximum height (h) and to cover a horizontal range (X). If the projectile is projected another time by the same canon at the same initial velocity by an angle 60o . The maximum height and the horizontal range in this case will be:
more than h , more than X
more than h , less than X
less than h , more than X
less than h , less than X
When two students measured the time taken by a copper sphere to fall freely from a building of 5 m high, they got the two readings below: The first student's reading: (0.1 s) – the second student's reading: (10 s). What do you think about the two readings?
A The two readings are reasonable.
The 1 st reading is reasonable while the 2 nd B is not.
The two readings are not reasonable
The 2nd reading is reasonable while the 1st D is not
The graph represents the position of two athletes, A and B, who are moving in a straight racetrack in the same direction versus time. At the instant when the athlete(A) is passing by the athlete (B):
Both displacement and velocity of athlete B are equal to those of A.
Both displacement and velocity of athlete B are more than those of A
Both displacement and velocity of athlete B are less than those of A.
Displacement of athlete B is more than that of A while and the velocity of athlete B equals that of A.
Figure (1) represents the change in position of a moving body (x) which is observed in equal intervals of time, each of 2s, while figure (2) represents (displacement – time) graph of another moving body (y). which statement describe correctly the motion of the two bodies?
They move at the same velocity.
Velocity of body (x) is twice that of body (y)
Velocity of body (x) is half that of body (y)
Velocity of body (x) is quarter that of body (y)
Using the following relations:
(Force = mass x acceleration)
(Potential Energy = mass x acceleration x height) So, the relation between The Newton (the measuring unit of force)and The Joule( the measuring unit of potential energy) is
Newton = Joule/meter
Newton = Joule. Meter
Newton = meter/ Joule.
Newton = Joule.
If the length of a rectangle = |5 ± 0.1 | m and
its width = |4 ± 0.2 | m. So, the rectangle area is :
| 9 ± 0.3 | m2
|20 ± 0.3| m2
|20 ± 1.4 | m2
|20 ± 0.5 | m2
The given figure illustrates two bodies K, Z of masses
2 kg and 5 kg respectively. If the body K affects the body Z on collision with a force of magnitude F, what is the force by which the body Z affects the body K?
- F
F
5/2 F
2/5 F
The graph represents the relation between the velocities of two bodies (C and B) versus time. What is the ratio between the acceleration of the body C to that of the body B?
(Given that : the slope of the line = tan Ø)
