Explanation:

An incline plane is 12-m long and 4-m high. A block is pulled up the ramp with a spring scale. The reading on the spring scale is 70-N. How many Newtons would the block actually weigh if you had to lift it the 4-m height?

Answers

Answer:

W = 210 N

Explanation:

For an ideal machine:

[tex]Work\ In = Work\ Out\\(P)(L)=(W)(H)[/tex]

where,

P = Effort = Spring Scale Reading = 70 N

L = Effort Arm = Length of inclined plane = 12 m

W = Actual Load (Weight) to be lifted = ?

H = Load Arm = Height = 4 m

Therefore,

[tex](70\ N)(12\ m) = (W)(4\ m)\\\\W = \frac{(70\ N)(12\ m)}{4\ m}[/tex]

W = 210 N

pls hurry <3

Answers

Answer:

175

Explanation:

its for Acellus

The potential difference is V=1.743*10^-7

The voltage is generally referred to as the electric potential difference and  it can be measured using a voltmeter. The electrical potential difference between the two plates is expressed as q=CV.

CALCULATION

we know,

q=CV

q={EA/d}*V

here q= 5.24*10^-8C

       A=8.22*10^-5m^2

       d=2.42*10^-8m

therefore , C={( 8.85*10^-12)*(8.22*10^-5)}/(2.42*10^-8)

                 C=3.006*10^-1

q=CV

q/C=V

V=1.743*10^-7

A ball is released from a height of 20 metres. Calculate; 1. The time it takes to fall 2. The velocity with which it hits the ground

Answers

Answer:

Final velocity of ball = 20 m/s

Explanation:

Given:

Height when ball released = 20meter

Find;

Time taken to fall

Final velocity of ball

Computation:

Initial velocity of ball = 0 m/s

Acceleration due to gravity = 10 m/s²

Using equation of motion;

S = ut + (1/2)(g)(t²)

20 = (0)(t) + (1/2)(10)(t²)

20 = 5(t²)

(t²) = 20 / 5

(t²) = 4

Time taken to fall = 2 second

V = u + at

V = 0 + (10)(2)

Final velocity of ball = 20 m/s

the shock absorbers in a car act as a big spring with k= 21900 N/m. when a 92.5 kg person gets in, how far does the spring stretch?

Answers

Answer: 0.04139m

Explanation:

First, we need to calculate the weight of the man which will be:

Weight = mass × acceleration due to gravity

Weight = mg

Weight = 92.5 × 9.8

Weight = 906.5N

Then, we calculate the force which will be:

F = kx

mg = kx

x = mg/k

x = 906.5/21900

x = 0.04139m.

The spring stretched for 0.04139m.

9. How is spring potential energy determined from a force versus position graph?

Answers

Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.

Explanation:

:)

By getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.

What will be the potential energy?

As we know that potential energy is defined as the energy possessed by the body due to its position with respect to other positions.

For an example the potential energy of an object if it is placed at height h will be due to the gravitational acceleration of the earth and is given by  [tex]PE=mgh[/tex]

Similarly, for a spring-mass system, the potential energy will be due to the weight of the mass that will be the force exerted by the mass on the spring so there will be an extension in the spring.

So this extension will be found out by the force and displacement  graph as the position of the mass attached to the spring goes down so the potential energy can be calculated as the

[tex]PE= F\times X[/tex]

[tex]F=mg[/tex]  weight of the mass

X= deflection of the spring

Thus by getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.

Healthy human lungs look pink and spongy from the outside. The left lung is a little smaller than the right lung to make room for the heart. The lungs and heart are both protected by the rib cage. In the lungs, each main bronchus branches off into many smaller bronchi. The bronchi become smaller and smaller, and the smallest bronchi are called bronchioles. There are about 30,000 bronchioles in each lung, each about the same thickness as a strand of hair. The inhaled air eventually ends up in tiny air sacs called alveoli at the end of each bronchiole. There are about 300 million alveoli in each lung. They are covered with capillaries, tiny blood vessels that are only one cell thick. Oxygen travels from the alveoli through the capillaries to the bloodstream, heart and other cells

The Hubble Space Telescope has a mass of 1.16*10^ 4 kg and orbits the Earth at an altitude of 5.68 * 10 ^ 5 above Earth's surface. Relative to infinitydetermine the potential energy the telescope at this location. Would the formula be Ep=-Gm1m2/r or positive G since it’s relative to infinity

Answers

Answer:

[tex]E=8.13\times 10^{12}\ J[/tex]

Explanation:

Given that,

The mass of a Hubble Space Telescope, [tex]m_1=1.16\times 10^4\ kg[/tex]

It orbits the Earth at an altitude of [tex]5.68\times 10^5\ m[/tex]

We need to find the potential energy the telescope at this location. The formula for potential energy is given by :

[tex]E=\dfrac{Gm_1m_e}{r}[/tex]

Where

[tex]m_e[/tex] is the mass of Earth

Put all the values,

[tex]E=\dfrac{6.67\times 10^{-11}\times 1.16\times 10^4\times 5.97\times 10^{24}}{5.68\times 10^5}\\\\E=8.13\times 10^{12}\ J[/tex]

So, the potential energy of the telescope is [tex]8.13\times 10^{12}\ J[/tex].

A ball experiences forces of 14 N [N] and 9.2 N [W]. A Free Body diagram is required. What is the acceleration of the ball if its mass is 225 g?

Answers

Answer:

First, we can define the North as the positive y-axis, and the East as the positive x-axis.

Here we have two forces:

F₁ = 14N to north

F₂ = 9.2 N to west.

Then the free body diagram will be the one that can be seen below:

Now we want to find the acceleration that the ball experiences if the mass is 225g

Knowing that 1k = 1000g, we can rewrite the mass as:

M = 0.225g

Here we also need to remember the second Newton's law:

F = M*a

Net force equals mass times acceleration.

First, let's find the net force:

F = F₁ + F₂ = 14N*(0, 1) + 9.2N*(-1, 0 )

F = (-9.2N, 14N)

The module of the force is then:

I F I = √( (-9.2N)^2 + (14N)^2) = 16.75 N

Then the acceleration is given by

16.75 N = 0.225kg*a

(16.75 N)/(0.225 kg) = a = 74 m/s^2
