A gorilla weighs 8.00x10^2N and swings from vine to vine. As the gorilla grads a new vine, both vines make an angle of 30 degrees with the verticle. In such a condition of static equillibrium what is the net force on the vine?
Answer:
461.88 N
Explanation:
Let tension in each vine be T .
The vertical component of this tension of both the vine will add up and balance the weight .
2T cos 30 = mg
2 T x cos 30 = 800
T = 800 / (2 x cos30 )
= 461.88 N

Explanation:
the weight of a person is 400N. he exerts 400N/m² pressure if he stands with both feet. Find the area of the floor covered by his both feet.
Answer:
1 m²Explanation:
The area of the floor covered by his both feet can be found by using the formula
[tex]a = \frac{f}{p} \\ [/tex]
f is the force
p is the pressure
From the question we have
[tex]a = \frac{400}{400} = 1 \\ [/tex]
We have the final answer as
1 m²Hope this helps you
An 80-kg student collides with a padded wall in the gymnasium while moving at 6.0 m/s.
Because he collided with a padded wall instead of a concrete wall, the time of collision was
increased by a factor of 10. What affect does this increase in collision time have upon the
force and the impulse that he experiences? Select two answers.
1. Colliding with the padded wall will make the force 10 times greater.
2. Colliding with the padded wall will make the force 10 times smaller.
Answer:
2. Colliding with the padded wall will make the force 10 times smaller
Explanation:
Impulse is the product of force and time. Its units are those of momentum. Assuming the change in momentum (impulse) remains the same, the increase in time means the force will be decreased by the same factor.
Colliding with the padded wall will make the force 10 times smaller

An object has an x-momentum of 8.5 kilogram-meters/second and a -momentum of 9.8 kilogram meters/second. What Is resultänt
momentum of the object?
OA 15.5 kilogram-meters/second
OB. 14.8 kilogram-meters/second
0c 12.97 kilogram-meters/second
OD. 16.8 kilogram-meters/second
Answer:
The resultant momentum is 12.97 kg.m/s. Choice: c
Explanation:
Momentum
The momentum is a vector that measures the quantity of motion that an object has. It's also known by the term "mass in motion".
As a vector, it can be expressed by its rectangular components:
[tex]\vec p = p_x\mathbf{i}+p_y\mathbf{j}[/tex]
The magnitude of the momentum is:
[tex]\mid \mid \vec p \mid \mid =\sqrt{p_x^2+p_y^2}[/tex]
The object described has an x-component of:
px=8.5 Kg.m/s
And a y-component of:
py=9.8 Kg.m/s
Thus, the magnitude of the momentum is:
[tex]\mid \mid \vec p \mid \mid =\sqrt{8.5^2+9.8^2}[/tex]
[tex]\mid \mid \vec p \mid \mid =\sqrt{72.25+96.04}[/tex]
[tex]\mid \mid \vec p \mid \mid =\sqrt{168.29}[/tex]
[tex]\mid \mid \vec p \mid \mid =12.97[/tex]
The resultant momentum is 12.97 kg.m/s. Choice: c

You are in a plane, and hit a bird as your flying, how can this impact produce a large impulse, despite the plane being much bigger
It effects the balance of the plane, and slows it. Also you are likely moving faster than the bird, and it would be almost as if you are hitting a brick. However when it makes the plane impulse then it means the sudden loss of speed (even if it is a small bird) that is keeping the plane in the air causes the planes engines to struggle for a short amount of time, while it tries to recover the little amount of speed it has lost (the engines HAVE to regain full speed or the plane will turn to the ground, maybe not ALL the way but it still will lower the nose.

1. Spring force is proportional to stretch distance, F=kd. Do you expect doubling the stretch distance double the force?
Yes
No
Answer:
Yes
Explanation:
The spring force is given as:
F = kd
F is the spring force
K is the spring constant
d is the magnitude of the stretch
Since k is a constant, therefore, doubling the stretch distance will double the force.
Both stretch distance and force applied can be said to be directly proportional to one another.
Answer:
Yes!

A student named Bob is on a bike and the mass is 50 kg. The force causes the student to accelerate at 3 m/s to the power of 2. Calculate the net force that causes this acceleration.???
Answer:
150 N
Explanation:
Force is equal to mass times acceleration. 50 kg accelerating at a mass of 3m/3² is undergoing a force of 150 m/s², or 150 Newtons
A baseball with a mass of 0.165 kg travels toward the outfield at a speed of 47 m/s. The outfielder’s glove brings the ball to rest in 0.20 s. What is the average force exerted on the ball by the glove?
Answer:
38.775N
Explanation:
A=(f-i)/t, where a=acceleration, f=final velocity, i=initial velocity, and t=time
A=(0-47)/0.2
A=-47/0.2
A=-235m/s^2
Use that acceleration and plug it into this equation
F=ma
F=0.165*-235
F=-38.775N
The glove exerts an equal and opposite force on the ball of 38.775N of force.

the stolen valor act
Answer:
The Stolen Valor Act of 2005, signed into law by President George W. Bush on December 20, 2006, was a U.S. law that broadened the provisions of previous U.S. law addressing the unauthorized wear, manufacture, or sale of any military decorations and medals. The law made it a federal misdemeanor to falsely represent oneself as having received any U.S. military decoration or medal. If convicted, defendants might have been imprisoned for up to six months, unless the decoration lied about is the Medal of Honor, in which case imprisonment could have been up to one year. In United States v. Alvarez, the U.S. Supreme Court ruled that the Stolen Valor Act was an unconstitutional abridgment of the freedom of speech under the First Amendment, striking down the law in a 6 to 3 decision.

Which factor leads to interference between waves? (2 points)
Select one:
a. A varying phase relationship between waves
b. Similar wave amplitudes
c. Unequal wavelengths
d. Radiation through different regions
Due to the sheer short wavelength, the angle at which constructive interference in between waves occurs is unequal wavelengths.
Unequal wavelengths:Two conditions must be met to create a steady and clear interference pattern: both wave sources must be cohesive, meaning they must emit identical waves with a consistent phase difference. The waves should be monochromatic, meaning that they will have only one wavelength.As a result, the interference between waves would be limited by unequal wavelengths.Find out more about the Unequal wavelengths here:

Electric power is to be generated by installing a hydraulic turbine-generator at a site 70 m below the free surface of a large water reservoir that can supply water at a rate of 1500 kg/s steadily. If the mechanical power output of the turbine is 800 kW and the electric power generation is 750 kW, determine the turbine efficiency and the combined turbine–generator efficiency of this plant. Neglect losses in the pipes.
Answer:
[tex]\eta_{turbine} = 0.777 = 77.7\%[/tex]
[tex]\eta_{combined} = 0.728 = 72.8\%[/tex]
Explanation:
First we calculate the power input to the turbine. The input power will be equal to the potential energy of water per unit time:
Input Power = [tex]P_{in} = \frac{Work}{Time} = \frac{Potential\ Energy\ of\ Water}{t} \\P_{in} = \frac{(mass)(g)(height)}{Time} = (mass flow rate)(g)(height)\\\\P_{in} = (1500\ kg/s)(9.81\ m/s^2)(70\ m)\\P_{in} = 1.03\ x\ 10^6\ W = 1030\ KW[/tex]
Now, for turbine efficiency:
[tex]\eta_{turbine} = \frac{Mechanical\ Power\ Out}{P_{in}}\\\\\eta_{turbine} = \frac{800\ KW}{1030\ KW}\\\\\eta_{turbine} = 0.777 = 77.7\%[/tex]
for generator efficiency:
[tex]\eta_{generator} = \frac{Power\ Generation}{Mechanical\ Power\ Out}\\\\ \eta_{generator} = \frac{750\ KW}{800\ KW}\\\\\eta_{turbine} = 0.9375 = 93.75\%[/tex]
Now, for combined efficiency:
[tex]\eta_{combined} = \eta_{turbine}\ \eta_{generator}\\\\\eta_{combined} = (0.777)(0.937)\\\eta_{combined} = 0.728 = 72.8\%[/tex]
A car and a delivery truck both start from rest and travel at the same rate, 5 m/sec. The truck travels for 5 seconds, while the car travels for 10 seconds. What is the traveled distance of the car compared to the truck? * a. Half as much b. The same c. Twice as much d. Four times as much
Answer:
c. Twice as much
Explanation:
The distance covered by the truck and the truck can be found by the following equation:
[tex]s = vt[/tex]
where,
s = distance covered
v = speed
t = time
FOR CAR:
[tex]s_{car} = (5\ m/s)(10 s)\\s_{car} = 50\ m[/tex]
FOR TRUCK:
[tex]s_{truck} = (5\ m/s)(5 s)\\s_{struck} = 25\ m[/tex]
Therefore,
[tex]\frac{s_{car}}{s_{truck}} = \frac{50\ m}{25\ m} \\s_{car} = 2s_{truck}[/tex]
The distance covered by the car is twice as much as the distance covered by the truck. So, he correct answer is:
c. Twice as much
