Which interaction does not take place due to field forces?

1 answer:

4 0

The interaction that does not take place due to field forces is the interaction between a pen and paper while you write.

<h3>What is the gravity law?</h3>

Gravity law is a well-established scientific theory that states objects can attract each other according to their masses.

This theory (gravity law) was developed by Sir Isaac Newton to explain the movement of objects.

In conclusion, the interaction that does not take place due to field forces is the interaction between a pen and paper while you write.

two projectiles are fired at equal speeds but differentangles. one is fired at an angle of 30 degrees and the other at 60degrees

zheka24 [161]

Answer:

a) 30 degree

Explanation:

As we know that time of flight of the projectile depends on the the vertical component of the velocity always

It is given as

$T = \frac{2v_y}{g}$

now we know that

$v_y = vsin\theta$

so we will have

$T = \frac{2vsin\theta}{g}$

since we know that two projectiles are projected at same speed but different angles

so smaller the angle will take smaller time

so it would be 30 degree projectile which will take smaller time

The cable supporting a 2130-kg elevator has a maximum strength of 2.18×104 n . what maximum upward acceleration can it give the

Vlada [557]

Answer;

=0.43 m/s²

Solution;

There will be the tension in the cable, T, upwards and the weight of the elevator, mg, downwards.

By Newton's second law, the sum of the forces will be equal to mass×acceleration.

Resultant force = m × a

Then T - mg = ma so the tension in the cable is

T = m(g+a)

The cable will break when T = 21,800 N

Solving for a, that happens when

a = 21800/2130 - g

= 10.23 - g (in m/s^2)

If you're using g = 9.8 m/s^2

Then the maximum acceleration allowed is 10.23-9.8 = 0.43 m/s^2
