What forces do a free body diagram analyze?
Bogdan [553]

Friction, gravity, normal force, drag force, tension force and human force are the forces that occurs on free body.

<h3>What are the forces in a free body diagram?</h3>

There are large number of external forces acting on an object such as friction, gravity, normal force, drag force, tension force and human force due to pushing or pulling. These forces can cause the motion of the free body which is present at rest form or can stop a body which is moving. A free-body diagram is a useful means of describing and analyzing all the forces that act on a body to determine equilibrium.

So we can conclude that friction, gravity, normal force, drag force, tension force and human force are the forces that occurs on free body.

Choose the +x-direction to point to the right. • Object 1 has a mass 1.66 kg and is moving to the right at 11.2 m/s. • Object 2
egoroff_w [7]

Answer:

M = 49.4kgm/s (towards the left)

Explanation:

Momentum is the product of mass and velocity of an object

Momentum = mass * velocity

Momentum of Object 1 with mass 1.66 kg moving to the right at 11.2 m/s, is expressed as:

M1 = 1.66 * 11.2

M1 = 18.592kgm/s

Momentum of Object 2 with mass 6.59 kg moving to the left at 10.4 m/s is expressed as:

M2 = 6.59 * -10.4

M2 = -68.536kgm/s (negative since it is moving towards the left)

The total momentum will be the sum of momentum along the x-component as shown:

M = M1+M2

M = 18.592kgm/s--68.536kgm/s

M = -49.944kgm/s

M = 49.4kgm/s (towards the left)

A rectangular loop of wire of width 10 cm and length 20 cm has a current of 2.5 A flowing through it. Two sides of the loop are
Dahasolnce [82]

Answer:

(a) 0.05 Am^2

(b) 1.85 x 10^-3 Nm

Explanation:

width, w = 10 cm = 0.1 m

length, l = 20 cm = 0.2 m

Current, i = 2.5 A

Magnetic field, B = 0.037 T

(A) Magnetic moment, M = i x A

Where, A be the area of loop

M = 2.5 x 0.1 x 0.2 = 0.05 Am^2

(B) Torque, τ = M x B x Sin 90

τ = 0.05 x 0.037 x 1

τ = 1.85 x 10^-3 Nm

Smoking can increase someone's risk for developing macular degration.<br> T/F
Brums [2.3K]
Macular Degration is the condition develops as the eye ages. Therefore doesn't have anything to do with smoking so this statement is "True" or the first option. M<span>acular Degration</span> caused by a problem with part of the eye called the macula. When the eye ages for most people it would cause blindness such how when the ear causes deafness. Most of the common cases would be smoking. This disease mainly effects a particular race which is Caucasian but it also comes into effect from aging, family history, (from other family members who had the disease) and being addicted to smoking. 

Hope this helps!

You are riding in a school bus. as the bus rounds a flat curve at constant speed, a lunch box with a mass of 0.470 kg suspended
valina [46]
Missing question: "<span> What is the speed v of the bus?"</span>

Solution:
Let's solve the problem by writing the equilibrium conditions on both x- and y- axis:
mg=T cos \alpha
m \frac{v^2}{r}=T sin \alpha
where mg is the weight of the lunch box, m \frac{v^2}{r} is the centripetal force, T is the tension of the string and \alpha=30^{\circ}.

The radius r is the one with respect to the vertical position of the string, therefore
r=L sin30^{\circ}=0.875 m.

From the first equation we find
T= \frac{mg}{cos \alpha}
and if we replace this into the second one, we find
m \frac{v^2}{r}=mg \tan \alpha
from which we can find the velocity:
v= \sqrt{rg \tan \aplha}= \sqrt{(0.875m)(9.81m/s^2)(\tan 35^{\circ})}=2.45 m/s
