Answer: B
Explanation:
Let us first resolve the forces.
Horizontal, the vectorial resolution is equal to zero. Since the positive direction and negative direction vector are of same magnitude. Therefore, summation of horizontal forces Fh = 0
Vertical resolution, the sum of forces will be Fv = 30 - 35 = - 5 N
Resultant force F = sqrt( Fv^2 + Fh^2)
Substitutes Fv and Fh. We get
R = sqrt ( 25) = 5N
We are given that the mass M = 2kg
From Newton second law,
F = Ma
Where a = acceleration
Substitute F and M and make a the subject of formula
5 = 2a
a = 5/2 = 2.5 m/s^2
Therefore, acceleration a of the object is 2.5 m/s^2 down.

power output
= work done / time
= 2 * 9.81 * 15 / 6
= 49.05W

Answer:
3 objects that depend on the electromagnetic spectrum would be television, radios, and the Microwave. This is due to the fact that radio waves depend on the electromagnetic spectrum and televisions and radios require radio waves. The microwaves also depend on the electromagnetic spectrum in order to make the Mircowave work
Explanation:
As per Newton's III law we can say that
Force applied by object 1 on object 2 is always equal in magnitude and opposite in direction of the force that object 2 apply on object 1.
So we can say it as

now here above question is based upon the same
if a bag of vegetables applied a force F = 22.5 N of the surface stand the the same surface will apply same magnitude of force in opposite direction on the vegetables bag
So our answer will be F = 22.5 N (upwards).
