Given:

Distance of satellite from Earth = 100 miles

Mass of satellite = 100 kg

If the mass of the satellite were doubled, let's find what would happen to the force of gravity of the satellite on earth.

Apply the gravitational force formula:

Where:

F is the force of gravity

m is the mass.

From the formula above, we can see the force of gravity (F), is directly proportional to the mass.

Since they are directly proportional to each other, if the mass is doubled, the force of gravity will also be doubled.

Therefore, if the mass of the satellite is doubled, the force of gravity of the satellite on the earth will also be doubled.

ANSWER:

Force of gravity will be doubled when the mass of the satellite is doubled.

The thinker belonging at the beginning of Raj’s timeline is Ptolemy.

Claudius Ptolemy was a mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science.

Ptolemy made his observations using nak-ed eyes. In his opinion, the Universe is ''a set of nested, transparent spheres, with Earth in the center. Ptolemy argued that the Moon, Mercury, Venus, and the Sun were all revolving around around Earth.

Although Ptolemy made significant contributions in Astronomy but he was wrong in his argument that the earth did not move at all.

Calculate the weight of the following masses, which are at the Earth's surface. For a mass of 1.5 kg, its weight is (W)=14.7N

Weight is a physical term that means that how much force of attraction is applied on the mass of the object. It can be measured in Newton and Dyne.

To calculate the weight we are using the formula here is,

W= mg

Here we are given,

m= mass of the object on earth. = 1.5 kg

g= The force of acceleration of the object. = 9.8m/s²

We have to calculate the value of the weight = W N.

Now we put the values in the above equation, we get

W=mg

Or, W=1.5*9.8

Or, W=14.7 N

Initial velocity is u=7.47 m/s

The angle is

The vertical height travelled, h=2.10 m

To find

The final speed of the pea.

Explanation

Along the vertical direction,

The final speed is given by the equation of kinematic

Putting the values

Along the horizontal direction,

the speed is constant throughout the projectile

Thus,

So the final velocity of the pea is

Conclusion

The final velocity is 3.81 m/s

Kinetic energy was "lost" in this inelastic collision is 151 J

The momentum is  given as :

m₁u₁  +  m₂u₂  =  m₁v₁  +   m₂v₂

The truck and car are locked together after the collision. The truck has same final velocity :

u = (( m₁ + m₂ ) v) / m₁

u = ( (9900 + 1000 ) × 3 ) / 9900

u = 3.30 m/s

now, the change in kinetic energy is given by :

ΔK.E = 1/2 (  m₁ + m₂) v² - 1/2 m₁ u²

ΔK.E = 1/2 ( 1211.11 ) - 1/2 ( 909.09)

ΔK.E = 605.55 - 454.54

ΔK.E = 151 J

Thus, A 9,900-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 5 m/s.  kinetic energy was "lost" in this inelastic collision is 151 J

The free body diagram representing this scenario is shown below

From the information given.

mass of car = 1200kg

Recall,

weight = mg

where

m = mass

g = acceleration due to gravity = 9.8 m/s^2

Thus,

weight of car = 1200 x 9.8 = 11760 N

Normal reaction, N has same magnitude with the weight but the direction is opposite. thus,

N = 11760 N

Frictional force = N x coefficient of friction

From the information given,

coefficient of friction = 0.67

Thus,

Frictional force = 11760 x 0.67 = 7879.2 N

Net force of the car = applied force - frictional force

applied force = 1.3 x 10^4 N = 13000 N

Thus,

Net force = 13000 - 7879.2 = 5120.8N

Recall,

net force = mass x acceleration

acceleration = net force/mass = 5120.8/1200 = 4.27 m/s^2

We want to calculate the time it will take Tyler to get to the gas station. We would apply one of Newton's equation of motion which is expressed as

s = ut + 1/2at^2

where

s = distance covered

t = time

a = acceleration

u = initial velocity

From the information given,

s = 15

a = 4.27

u = 0 because the car was at rest(Since it was broken down)

By substituting these values into the equation, we have

15 = 0 x t + 1/2 x 4.27 x t^2

15 = 0 + 2.135t^2

15 = 2.135t^2

Dividing both sides of the equation by 2.135, we have

15/2.135 = 2.135t^2

t^2 = 7.026

t = square root of 7.026

t = 2.65

The time required is 2.65 s

The earth is accelerating toward the apple at a rate of 6.2 × 1025 m/s2.

The apple weighs m = 0.37 kg.

The apple's speed when it approaches the earth's surface is 9.8 meters per second.

Earth's mass, M, is 5.98 × 1024 kg.

Using Newton's Second Law of Motion, we may now:

The strength of the force exerted by Earth on the apple is,

F = ma

⇒ F = 0.37 × 9.8

⇒ F = 3.626 N

We are informed that the apple must exert an equal but opposite force on Earth in accordance with Newton's third law of motion.

Therefore, the force exerted by the apple on Earth will be of the following magnitude:

F = 3.626 N

Let "A" be the acceleration of the earth relative to the apple in m/s2.

Thus,

The following will be used to determine how quickly the earth is moving toward the apple:

F = MA

⇒ 3.626 = [5.98 × 10²⁴] × A

⇒ A = 3.626 / [5.98 × 10²⁴]
