Answer:
F = 0.408 N
Explanation:
It is given that,
Weight of a wooden block, W = 8 N
Weight, W = mg
m is mass of wooden block
Acceleration of the block, a = 0.5 m/s²
Force, F = ma
So, the magnitude of force applied to the wooden block is 0.408 N.
The angle is 34.4°.
The radius of a circle and the central angle determine the length of an arc. We are aware that the arc length is equivalent to the circumference for an angle of 360 degrees (2π). As the proportion between angle and arc length is constant, we can say that:
L / θ = C / 2π
As circumference C = 2πr,
L / θ = 2πr / 2π
L / θ = r
We find out the arc length formula when multiplying this equation by θ:
L = r * θ
The arc length is equal to the radius multiplied by the central angle.
Radius of the circle, r = 2.70m
Length of the arc, L = 1.60 m
L = rθ
θ = L / r
= 1.60 / 2.70
= 0.6 rad
θ = (0.6 rad × 180° ) / π rad
= 34.4°
Therefore, the angle is 34.4°.

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Answer:
The product of mass and velocity is the correct answer
Explanation:
Momentum is defined as mass × velocity
p = mv
