Answer:

The gravitational force between two objects is written as:

F = G*m1*m2/r^2

Where:

G = 6.67*10^(-11) m^3/kg*s

m1 and m2 are the masses of the objects.

r is the distance between the objects.

In this case, we know that:

F = 0.0005 N

r = 10m

and because the two spheres are identical, we have that:

m1 = m2 = M

then we have the equation:

0.0005 N = (6.67*10^(-11) m^3/kg*s)*(M^2/(10m)^2)

0.0005 N*(10m)^2/(6.67*10^(-11) m^3/kg*s) = M^2

√( 0.0005 N*(10m)^2/(6.67*10^(-11) m^3/kg*s) ) = M = 27,379.3 kg

The mass of each sphere is 27,379.3 kg

Answer:

looks like law of inertia

Explanation:

Answer:

The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. Newton's first law of motion is often stated as. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

The speed of the wave is 14.4 m/s.

Speed is the rate of change of distance.

To calculate the speed of the wave, we apply the formula below.

Answer:

the total kinetic and potential energy of its particles

Explanation:

In every object, there are two types of energy which can be found inside them-Kinetic and Potential Energy. For example, a solid object placed on a stationary table has a potential energy due to the vibration of the molecules of the object.

As the object is moved across the table, it has kinetic energy. The combination of both energy is known as thermal energy. An increase in both energy leads to increase in the thermal energy of a given object.

Answer:

B

Explanation:

Since

K.E = 1/2 mv^2

P.E = mgh

Answer:

When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.

The centripetal force is required.

The centripetal force is 243.47 N.

m = Mass of runner = 78.6 kg

v = Velocity of runner = 8.8 m/s

Answer:

Because radiation does not require material medium for its propagation.

Explanation:

Radiation is one of the types of modes of heat transfer that takes place majorly in gases. Heat energy can be transferred through gases by radiation without heating up the intervening medium. Even, if the available molecules of gases are evacuated, the heat energy would propagate.

Thus, student's hands were not heated by convection since convection is a mode where material medium is required for propagation of heat energy.

Answer:

Mr. Turner will not be able to stop in time.

a = - 71.2 m/s²

s₁ = 11.67 m

Explanation:

Since, Mr. Turner is driving at 45.56 m/s and his reaction time for applying brakes is 3/4th of a second. So, the distance covered by car in this time will be:

s₁ = vt

where,

s₁ = distance covered by car before applying brakes = ?

v = speed of car = 15.56 m/s

t = reaction time = 3/4th of second = 0.75 s

Therefore,

s₁ = (15.56 m/s)(0.75 s)

s₁ = 11.67 m

and the distance required for the car to stop after applying brakes is:

s₂ = 1.7 m

So, the total distance traveled by car before stopping will be:

s = s₁ + s₂

s = 11.67 m 1.7 m

s =  13.37 m

since, the driver was 13.3 m ahead.

Therefore, Mr. Turner will not be able to stop in time.

To find the deceleration of Mr. Turner after applying brakes we use 3rd equation of motion:

2as₂ = Vf² - Vi²

where,

a = deceleration = ?

Vf = Final Velocity = 0 m/s

Vi = Initial velocity = 15.56 m/s

Therefore,

2a(1.7 m) = (0 m/s)² - (15.56 m/s)²

a = - (242.1136 m²/s²)/3.4 m

a = - 71.2 m/s²

Explanation:

Answer:

485.62 N

Explanation:

To obtain the magnitude of unbalanced forces acting on the body;

Unbalanced Force = Horizontal Component of Applied Force - Frictional Force

Frictional Force = Horizontal Component of  Applied Force - Unbalanced Force

f = frictional force  = ?

F = Applied force  = 593 N

m = mass of person = 49 kg

a = acceleration = 0.57 m/s²

θ = Angle with horizontal = 30°

Hence;

Horizontal Component of  Applied Force = (593 N)(Cos 30°)

Unbalanced Force = (49 kg)(0.57 m/s²)

f = (593 N)(Cos 30°) - (49 kg)(0.57 m/s²)

f = 513.55 N - 27.93 N

f = 485.62 N

Answer:

Explanation:

Kinetic energy increases as mass and speed are increased

Answer: 10.05m/s²

Explanation:

Force acting on the plane has a magnitude of 1900N.

Mass of plane = 860kg

We then calculate the acceleration which will be:

= 1900 / 860

= 2.21 m/s²

Since acceleration due to gravity is equal to 9.8m/s², then the net acceleration will be:

= ✓(2.21² + 9.8²)

= ✓(4.88 + 96.04)

=✓100.92

= 10.05m/s²

Answer:

Explanation:

Answer:

skateboard b

Explanation:

p=mv

skateboard a

p=(60kg)(1.5m/s)=90kg*m/s

skateboard b

p=(50kg)(2m/s)=100kg*m/s

Skateboarder B has the greater momentum because the momentum of A is 90 kg m/s and the momentum of B is 100 kg m/s so B has the greater momentum.

Momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum. Check out Newton's laws of motion.

According to Newton's second law, if a particle is subjected to a constant force for a specific amount of time, the result of the force and time (referred to as the impulse) is equal to the change in momentum. On the other hand, a particle's momentum represents the length of time needed for a consistent force to bring it to rest.

According to the question,

For Skateboarder A :

momentum = 60 × 1.5

momentum = 90 kg m/s

For Skateboarder B :

momentum = 50 × 2

momentum = 100 kg m/s.

Hence, B has greater momentum than A.

Answer:

The force will have to increase

Explanation:

Since Juan has upgraded from a sports car to a large truck, based on Newton's second law of motion, the force needed to keep the truck going at the same speed will have to increase.

 According to Newton's second law "the force on an object is equal to the product of its mass and acceleration".

       Force  = mass x acceleration

A truck has a larger mass compared to a sports car.

By virtue of this, to make sure both automobiles attain the same speed, the force powering them to accelerate must be the same.

 Therefore, the force from the engine must increase.

Given: 6 questions with certain values of mass and acceleration.

To find: The amount of force?

Solution:

An object with a mass of 2.0 kg accelerates 2.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

                    F = m x a = 2 x 2 = 4 N

An object with a mass of 5.0 kg accelerates 8.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

                     F = m x a = 5 x 8 = 40 N

An object with a mass of 1500 g (grams) accelerates 10.0 m/s2 when an unknown force is applied to it. What is the amount of the force?

Now in this mass is in grams, so converting it kg, we get:

                    1500/1000 kg = 1.5 kg

                   F = m x a = 1.5 x 10 = 15 N
