Why would the force of gravity change between the earth and sun when the mass of the earth increased

Answers

Answer 1
Answer:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Answers

The magnitude of the centripetal acceleration of the bicycle wheel is 40 m/s².

Centripetal acceleration of the wheel

The centripetal acceleration of the bicycle wheel is the inward or radial acceleration of the bicycle on the circular path.

The magnitude of the centripetal acceleration of the bicycle wheel is calculated as follows;

a = ω²r

ω is angular speed

r is the radius of the circular path

a = (10)² x 0.4

a = 40 m/s²

600kg

The mass of the rocket will be 600 kg.In the International System of Units (SI), the kilogram is the unit of mass.

What is mass?

Mass is a numerical measure of inertia, which is a basic feature of all matter. It is, in effect, a body of matter's resistance to a change in speed or position caused by the application of a force.

In the International System of Units (SI), the kilogram is the unit of mass.

The given data in the problem is;

The net constant force is, F= 1500 N

The acceleration is,a=2. 5 m/s²

The mass of the rocket is,m=?

[tex]\rm F= mass \times acceleration \\\\ m = \frac{F}{a} \\\\ m= \frac{1500}{2.5}\\\\ m = 600 \ kg[/tex]

The FRC robot is rushing to pick up a game ball to shoot. The robot
is at rest and then it travels 30m in 1.96s. What is the robot's
acceleration in this time?

Answers

Answer:

15.61 m/s^2

Explanation:

From 3 rd equation of motion

s=ut+1/2at^2

given s = 30

u= 0 ( as body was at rest)

t= 1.96s

30=0*1.96+1/2a(1.96)^2

A bottle of soda always has a space between the cape and the top of the liquid. Explain

Answers

Answer:

All soft drinks contain water. When soft drink bottles are chilled in sub-zero temperatures, the water on account of its anomalous expansion expands. Thus, to provide space for expanding water, soft drink bottles are not completely filled as otherwise they will burst.

Explanation:

Answer:

Soft drink bottles are filled leaving some space between the lid/cap and the liquid level.

Explanation:

The reason is that the soft drinks are cooled below room temperature.  Sometimes they are kept in the hot Sun and weather.  They are subject to a big temperature variation.  Also, there are gases like CO2 mixed in the drink.  So the gases come out of the liquid and expand due to heat.  That creates high pressure.

Water expands when it is cooled to 4 deg. C.  But the bottle (glass) contracts when it is cooled.  So if there is no air gap,  then volume of water (cool drink) will become more than the inside volume of the bottle.  Then the bottle will break due to pressure from water expansion around 8 deg. to 4 deg.C.

When a bottle is opened, due to pressure difference, and temperature difference, the gases come out of drink in the form of bubbles.  So cold drink overflows out.

Also, the soft drink bottles are capped tightly.  When an opener is used to open it using some force upwards, the pulling force also moves the soft drink bottle upwards.  So just after the lid comes off, the top part of the drink comes out due to the pull.  So some drink spills on people who open or, it falls outside.

In order to prevent these problems, some gap is left open between the surface of the soft drink and the top of the bottle.

What is the difference between gravity and acceleration?

Answers

Aceleration refers to motion but gravity refers to force



Acceleration is change of velocity with time while gravity is the force of attraction pulling objects. When this force pulls an object it tends to move with a certain type of acceleration called acceleration due to gravity. This is equal to 9.8 m / s^2 for earth

Acceleration is the rate of change in velocity. While g is the acceleration due to gravity. The pace at which a body's velocity varies is represented by acceleration, which is a vector quantity.

What is acceleration?

The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.

[tex]\rm a = \frac{v-u}{t}[/tex]

u is the initial speed

v is the final speed

t is the time interval

a is the acceleration of the ball

Gravitation is a natural law by which all things with all matter are attracted towards one another.

g is the acceleration due to gravity. whose value is equal to 9.81 m/sec².The value of the gravitational acceleration varies according to the height and the planet.

The value of the gravitational acceleration on the earth is 9.81 m/sec².While the value of g at the moon is 1.6333 m/sec².

Answers

The necessary light intensity of the disk if the disk has mass 3.89 g and radius 2.40 cm is 6.483 x 10^12cd.

Calculations and Parameters:

a. Given that:

i= intensity of light m= mass of disk g= gravitational acceleration c= speed of light a= cross-sectional area of the disk

I = P/A

= Force x Speed/Area

Gravitational force, F= GM1M2/r^2

F= ma, F= mg

I= mg x c/q

That is,

i= mass x gravitational acceleration x speed/area

b.

Mass= 3.89g

Radius, r= 2.40cm

i=?

i= mg x c/a

Speed of light= 3.0 x 10^8 m/s
