<h2>Answer: C.Monogamy </h2>

Explanation:

Monogamy is a term that refers to the sentimental and sexual bond that <u>does not allow the multiplicity of spouses. </u>

In a circus act, a 70 kg clown is shot from a cannon with an initial velocity of 17 m/s at some unknown angle above the horizont
EleoNora [17]

Answer:

K_{2}=7302.4J

Explanation:

Given the initial velocity of the clown, his mass and final height we can calculate the final kinetic energy using the <em><u>conservation of total mechanical energy</u></em>

K_{1}+U_{1}=K_{2}+U_{2}

K_{2}=K_{1}+U_{1}-U_{2}

K_{2}=\frac{1}{2}mv_{1}^{2}+mgh_{1}-mgh_{2}

Since h_{1}=0

K_{2}=\frac{1}{2}mv_{1}^{2}-mgh_{2}

K_{2}=\frac{1}{2}(70kg)(17m/s)^2-(70kg)(9.8m/s^2)(4.1m)=7302.4J

K_{2}=7302.4J

A box weights 50kg applies friction force of 125N. You apply a force of 150N going in the right direction. What is the total net
Pachacha [2.7K]

Answer:

Net force  = 25N  and in the right direction

Explanation:

mass of box, m = 50kg

Force of block = 150N

Friction force = 125N

Net force  = Force Applied - Friction force =  F - F_f

150 - 125 = 25N

the force applied to the block is greater than the friction force. there the force applied will overcome the friction force and move in the right direction of the force applied
