I WILL GIVE BRAINLIEST!!!

Answer:

it would be 3

Explanation:

because you have to divide the length by the height of the incline.

The mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.

Mechanical advantage is a measure of the ratio of output force to input force in the system, it is used to obtain the efficiency of a mechanism.

The formula for the mechanical advantage of the inclined plane is found as;

[tex]\rm Mechanical \ advantage = \frac{length}{height} \\\\ Mechanical \ advantage =\frac{9}{3} \\\\ Mechanical \ advantage =3[/tex]

Hence the mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.

Answer:

We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.

Hence, option D is correct.

Explanation:

Given

To determine

Mass m = ?

Important Tip:

Using the formula

[tex]F = ma[/tex]

where

now substituting F = 500, and a = 75 m/s² in the formula

[tex]F = ma[/tex]

[tex]500 = m(75)[/tex]

switch sides

[tex]m\left(75\right)=500[/tex]

Divide both sides by 75

[tex]\frac{m\cdot \:75}{75}=\frac{500}{75}[/tex]

simplify

[tex]m=\frac{20}{3}[/tex]

[tex]m=6.7[/tex] kg

Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.

Hence, option D is correct.

Answer:

375J

Explanation:

W=F x d

=250 x 15

=375J

The work W is equal to the force f times the distance d, or W = fd, to mathematically describe this idea. If the force is applied at an angle to the displacement, the work is W = fd cos.

Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. In its simplest form, For a constant force that is oriented in the same direction as the motion, it is easiest expressed as the product of the force's magnitude and the distance travelled.

A desk is being subjected to applied force if someone is pushing it across the room. The person's force applied to the desk is known as the applied force.

Mass and weight are not the same.The normal force is the supporting force exerted on an object when it collides with another stable object.

Therefore, W=F × d =250 × 15 =375J

Organic compounds are important because all living organisms contain carbon. They are the basic components of many of the cycles that drive the earth. For example, the carbon cycle that includes the exchange of carbon between plants and animals in photosynthesis and cellular respiration.

Answer:

Coal is fossil fuel extracted from earth and since it takes a long time to replenish, it is called a non renewable source of energy

Explanation:

Coal is formed from the fossil fuel that lie deep beneath the earth crust . These fossil fuels are dead remains of living organism that burried beneath the earth crust million of years ago.

Coal is non renewable because if once it gets depleted it will take a very very long time to replenish.

Answer: Coal is fossil fuel extracted from earth and since it takes a long time to replenish, it is called a non renewable source of energy

Answer:

15 meters/second

Explanation:

Answer:

Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects, and is inversely proportional to the square of the distance between them. The factors G, M, and r are the same for all masses at the surface of the Earth.

Answer:

c

Explanation:

because newton's second law states that F= MA

which suggests that if M increases, F also increases which is the force,

let me give you a tip, during exam, just type any random numbers into the formula, like at first you type 5 into the M, then increase M, by putting 10 into the M , keep the acceleration the same for this, okay?

you will see that the force will increase,

by this I mean that option says largest mass, so the force will also be very big because in reality do you use more force on heavier box or a lighter one to push it across the room?

so larger mass, larger force, greater acceleration

but the question is not being clear, whether to the force remains constant for every object, if it does then A is false . and B is false because if the forces is constant, and it is light, it would require a small amount of force ,

but the other options, gave us a clue about the force so you can choose either c or d but see the explanation above,

the only corrext option will be c.

if not, please report this, someone will have a go at it

Answer:CADB

Explanation:

Answer:

the distance covered by the car is 95.4 m.

Explanation:

Given;

initial velocity of the car, u = 36 m/s

acceleration of the car, a = -2.8 m/s²

time of motion of the car, t = 3 s

The distance covered by the car is calculated as;

s = ut + ¹/₂at²

s = 36(3) + ¹/₂ x (-2.8)(3)²

s = 108 - 12.6

s = 95.4 m

Therefore, the distance covered by the car is 95.4 m.

Answer:

d. 12.30 grams

Explanation:

Given the following data;

Force = 652 N

Acceleration = 53 m/s²

To find how much the object weigh, we would need to determine its mass;

Force = mass * acceleration

652 = mass * 53

Mass = 652/53

Mass = 12.30 grams.

Therefore, the object weighs 12.30 grams.

Answer:

Workdone = 1960 Joules.

Explanation:

Given the following data;

Mass = 5kg

Force = 49N

Height (distance) = 40m

To find the workdone;

Workdone = force * distance

Substituting into the equation, we have;

Workdone = 49*40

Workdone = 1960 Joules.

Therefore, the amount of work done on the bowling ball to lift it is 1960 Joules.

Answer: The  Answer Is A

Explanation:

Were Gonna convert minutes to hours

12 minutes = 12/60  hours = 0.2 hours

Now we estimate the average velocity of the distance traveled over this time

1.5 / 0.2 km/h = 7.5 km/h

Answer: When objects fall to the ground, gravity causes them to accelerate.

Explanation: Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.

Explanation:

actually, the question would need to give you what is the gravitational force, so let's take the average of the gravitational for me which is 10 N /kg

and the formula for finding weight is

W = mg

W = (5)(10)

W = 50 N
