What two horizontal forces are present as a car is pushed down the driveway?(1 point)

push, velocity
power, friction
power, weight
push, friction

The equation that could be used to find the velocity of the satellite if it is placed in a low Earth orbit is [tex]v = \sqrt{\frac{Gm_p}{200 \ km} }[/tex].

The given parameters;

A low Earth orbit is an orbit around the Earth with altitude in the range of 250 km and 2000 km.

The gravitational potential or the work done in bringing the satellite to the low Earth orbit is given as;

[tex]U = \frac{GMm_p}{R} \\\\[/tex]

where;

let the value of R = 400 km

Note: any value between 250 km and 2000 km can be used BUT 400 km is the only value within this range that can be found in the given options as you will see at the end of the solution.

[tex]U = \frac{GMm_p}{400 \ km}[/tex]

The kinetic energy of the satellite at the low Earth orbit is equal to the gravitational potential energy due to the altitude of the low Earth orbit.

[tex]K.E = U\\\\\frac{1}{2} Mv^2 = \frac{GMm_p}{400 \ km} \\\\v^2 = \frac{2Gm_p}{400 \ km}\\\\v^2 = \frac{Gm_p}{200 \ km}\\\\v = \sqrt{\frac{Gm_p}{200 \ km}}[/tex]

Thus, the equation that could be used to find the velocity of the satellite if it is placed in a low Earth orbit is [tex]v = \sqrt{\frac{Gm_p}{200 \ km} }[/tex].

Answer:

V = W = 12 J/C * 150 C = 1800 J      work in moving 150 C of charge

P = W / t = 1800 J / 60 s  = 30 watts

Answer:

30 Watts

Explanation:

We're provided with the following information:

= 60 seconds

Current is the rate of flow of charge ,i. e., The amount of charge flowing "per second":

[tex]\boxed{\mathfrak{Current(I)=\frac{Charge(Q)}{Time(T)} }}[/tex]

We have:

Finding the current flown using the above mentioned formula:

[tex]\implies \mathsf{I=\frac{150}{60} }[/tex]

[tex]\implies \mathsf{I=\frac{5}{2} }[/tex]

=> I = 2.5 A

A(Amperes) is the SI unit of Current

We've a relation between Power, Current and Voltage, derived with the help of  "Joule's Law of Heating", and that is:

[tex]\boxed{\mathfrak{Power(P)=Voltage(V) \times Current(I)}}[/tex]

We can finally find Power, Since we have:

=> P = 12 × 2.5

=> P = 30 W

W, Watts, is the Si unit of Power

Answer:

The pressure remains the same.

F = P * A  the amount of force transmitted would double if only the input area is changed. Pressure is the same at all points in the system.

Hi there!

[tex]\large\boxed{\text{B. 32.73N}}[/tex]

To calculate the tension, we must calculate the acceleration of the system.

Begin with a summation of forces:

∑F = -M₁gsinФ + T - T + M₂g

Simplify and solve for acceleration: (Tensions cancel out)

[tex]a = \frac{-M_1gsin\theta + T - T + M_2g}{M_1+M_2}[/tex]

Plug in values. Let g = 10 m/s²

[tex]a = \frac{-3(10)(sin30)+8(10)}{3+8} = 5.91 m/s^{2}[/tex]

Now, to find tension, let's sum up the forces acting on ONE block. For simplicity, we can look at the hanging block:

∑F = -T + W

ma = -T + W

Rearrange to solve for T:

T = W - ma

We know the acceleration, so plug in the values:

T = (8)(10) - (8)(5.91) = 32.73 N

a). 1.2 s

b). 3.81 m

c) v= 6.8 m/s

d) v= 27.05 m/s

Speed is define as the distance per unit time. It is also define as how fast an object is  moving.

According to the question:

Height = 1.5 m , speed = 7.0 m/s.

a)By using 1st equation of motion

[tex]V = V_{0} + g*t.\\V = 0 \\V_{0} = 7.0 m/s.g = -9.8 m/s^2\\0 = 7 + (-9.8 m/s^2)*t\\t = 1.2 s[/tex]

b.

[tex]h = 1.5 + V_{0} *t + 0.5g*t^2\\V_{0} = 7.8 m/s\\t = 1.2s , g = -9.8 m/s^2\\h = 3.81 m[/tex]

c.

[tex]V^2 = V_{0} ^2 + 2g*d\\V_{0} = 7.8 m/s\\g= -9.8 m/s^2.\\d= 2.2-1.5 = 0.7 m\\V = 6.8 m/s[/tex]

d.

[tex]V^2 = V_{0} ^2 + 2g*h\\V_{0} = 0\\g = +9.8 m/s^2.\\h = 6.8 m\\V = 27.05 m/s[/tex]

Answer:

I believe the answer is D.

Explanation:

It would have been helpful if there had been more information included with this problem, but it would make sense that the answer is D.  If there is a winter between time 1 and 3, bison that are not well-suited to the weather, (skinny and smooth) will die off, and only the ones well-suited to winter weather will survive to produce offspring.

During the snowy winter, the fat, shaggy bison survived while most of the other bison died. The next year, the shaggy bison produced mostly shaggy offspring. So, option D.

An organism, such as a plant or animal, can acquire any heritable characteristic that aids in its ability to survive and procreate in its environment. This is known as adaptation.

Here,

A bison has a summer coat that is lighter in weight and lighter in colour than its shaggy, long, dark-brown winter coat.

In comparison to female bison, men are noticeably bigger and heavier. Wood bison typically fluctuate in size from larger to smaller, compared to plains bison.

When the grassland is hot and there is no shade, the bison's short, thinner hair at the back helps keep it cool. In times of heavy snow and wind, bison move through the landscape while facing the elements. This is made feasible by the thick coat. On chilly days, the coat's dark brown to nearly black colour aids to absorb solar heat. Similar to dogs, bison get a heavier winter coat in the autumn and maintain it into April. By the end of spring, they have shed and grown a new, lighter coat.

Hence,

During the snowy winter, the fat, shaggy bison survived while most of the other bison died. The next year, the shaggy bison produced mostly shaggy offspring. So, option D.

This process is thought to have been the main source of energy for the sun in the early stages of its development before nuclear fusion reactions in the sun's core became the dominant source of energy.

Gravitational contraction is the process by which a celestial body, such as a star, generates energy through the release of gravitational potential energy as it contracts and becomes denser.

Here,
This process is thought to have been the main source of energy for the sun in the early stages of its development before nuclear fusion reactions in the sun's core became the dominant source of energy.

As the sun contracted and became denser, the temperature and pressure in its core increased, leading to the initiation of nuclear fusion reactions. These reactions transformed hydrogen into helium and released a tremendous amount of energy in the form of light and heat, which has sustained the sun for billions of years.

Forces of inertia

Answer: The gravitational force between two objects depends only on their masses.

Explanation:

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Therefore, gravity relies on mass and distance, not just mass.
