1) The tension in the horizontal massless cable CD is, 446N
2) The vertical component of the force exerted by the pivot A on the aluminum pole 328.3N
3)The horizontal component of the force exerted by the pivot A on the aluminum pole is,446N
To find the answer, we need to know about the tension.
<h3>How to find the tension in the horizontal massless cable CD?</h3>
- To find the tension in horizontal cable CD ,we have to draw the free body diagram of the masses.
- Given that,
- In the free body diagram, let's balances all the vertical and horizontal forces to get the tension on CD.
<h3>How to find the vertical and horizontal components of the force exerted by the pivot A on the aluminum pole?</h3>
- The net force along vertical direction can be written as,
- The net force along the horizontal direction is,
Thus, we can conclude that, the tension in the horizontal massless cable CD and the horizontal component of force exerted by the pivot A on the aluminum pole are same and is equal to 466N, and the vertical component force exerted by the pivot A on the aluminum pole is 328.3N.

The change in velocity with a constant resistance of the body during the first 20 s = -10/9 ms⁻¹
The change in velocity of the body during the first 20 s = 10/9
Mass = 18 kg.
Resistance to motion = 20 N
Decreases at a uniform rate from 60 N to 35 N
time = 25 s,
Force which decreases at a uniform rate = (60 - 35)/25 = 25/25
= 1 NS⁻¹
Initial velocity,
F = p/t
= mv/t = 18*v/t
V = (60 - 20) /18 = 20/9
Final velocity,
Decreases at a uniform rate = = 1 NS⁻¹
at 20 s = 20 N decrease
total force applied at 20 s without resistance = 60 -20-20 = 20.
V final = 20/18 = 10/9
Change in velocity = V final - v initial
= 10/9 - 20/9
= -10/9
Resistance is described as a refusal to provide in or to something that slows down or prevents some thing. An instance of resistance is a toddler combating against her kidnapper. An instance of resistance is wind against the wings of a aircraft.
The unit of the electrical resistance, measured with direct present day, is the ohm (Ω), named after the German physicist and mathematician Georg Simon Ohm. in step with ohm's regulation, the resistance R is the ratio of the voltage U across a conductor and the modern R = U / I.

The spring constant, k, will be equal to 18 N/m. The spring constant is defined as the force-to-displaced-length ratio.
<h3 /><h3>What is the spring constant?</h3>
Spring constant is defined as the ratio of force per unit displaced length.
Given data;
Mass of block,m=0.250 k
Amplitude,A = 0.125 m
Velocity,V=3.00 m/
Spring constant, K=?
The spring constant formula when the spring oscillates at the specified amplitude A:
Hence, the spring constant, k will be 18 N/m

Last one: Every object in the universe attracts every other object
The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).
