djverab [1.8K]2 years ago
4 0

Vector quantity is defined by direction as well as magnitude both

so now lets discuss all option

1) distance = it is total path length between two points so there is no direction needed in it so it is scalar

2) Speed = it is ratio of total distance covered and total time, so it also do not require any direction.

<em>3)velocity = it is ratio of displacement and time, and displacement is always given with direction so velocity is a vector quantity</em>

4) time = time is the measurement of the interval of two events and we do not require any direction in it so its a scalar quantity.

To loosen the lid on a jar of jam 8.9 cm in diameter a torque of 7.5 n·m must be applied to the circumference of the lid. if a j
KIM [24]
Refer to the diagram shown below.

F =  the minimum force required for opening the lid
r = 8.9/2 = 4.45 cm = 0.0445 m
P =  the applied force, aplied at a distance of 13 cm = 0.13 m.

Because the required torque is 7.5 N-m, therefore
(0.13 m)*(P N) = 7.5 N-m
P = 57.6923 N

The equation for the lever requires that
0.13P = 0.0445F = 7.5
Therefore
F = 7.5/.0445 = 168.54 N

Answer: 168.5 N
