Which of the following objects in motion has the highest inertia?


A.) A 5.0 kg mass moving at 2.0 m/s

B.) A 8.0 kg mass moving at 9.0 m/s

C.) A 6.0 kg mass moving at 10. m/s

D.) A 15 kg mass moving at 2.0 m/s

Answers

Answer 1

Answer:

D.) A 15 kg mass moving at 2.0 m/s

Explanation:

The inertia of an object is most directly related to its mass and not the magnitude of the velocity.

So, the higher the mass of an object, the more its inertia.

According to Newton's first law of motion "an object will remain in its state of rest or of constant motion unless it is acted upon by an external force".

Inertia is the tendency of a body to remain in a state of rest either by virtue of its static position of constant motion. The larger the mass, the more this tendency. An object with a large mass will take more force to bring it from rest or change its motion.

fertilizers?
A. oxygen
B. hydrogen
C. nitrogen
D. carbon

Answers

To Find :

Which element accumulates in the environment due to the use of  fertilizers.

Solution :

Most of the fertilizers used in daily practice are nitrogen fertilizers .

When soil became waterlogged, soil organisms take the oxygen they need from nitrates, leaving the nitrogen in a gaseous form which escapes into the air.

Also, nitrogen is very stable and did not participate in most of the reactions.

So, nitrogen is accumulates in the environment .

Therefore, option C. is correct.

An object is moving east, and its velocity changes from 66 mvs to 26 mvs in 10 seconds. Which describes the
acceleration?
negative acceleration of 4 mvs
positive acceleration of 4 ms
positive acceleration of 9 m/a
negatlveo acceleration of 9 m/s

Answers

Answer:

negative acceleration of 4m/s²

Explanation:

Given parameters:

Initial velocity  = 66m/s

Final velocity = 26m/s

Time taken = 10s

Unknown:

Description of the acceleration  = ?

Solution:

Acceleration is the rate of change of velocity with time.

It is mathematically expressed as;

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

v is the final velocity

u is the initial velocity

t is the time taken

  Now insert the parameters and solve;

    Acceleration  = [tex]\frac{26 - 66}{10}[/tex]   = -4m/s²

So, we see a negative acceleration of 4m/s²

You have a 100 N object with a normal force of 100 N. You apply a 50 N push to the right, but a friend is hiding on the other side of the object and is also pushing with a force of 60 N. What is the net force on the object?

Answers

Answer:

100.49N

Explanation:

First we must know that the normal force acts in the vertical direction;

The force required to push to the right and left acts in the horizontal direction;

Sum of force along the horizontal Fx = 50N - 60 N = -10N

Force along the vertical Fy = 100N

The net force on the object is calculated as;

F = √(Fx)² + (Fy)²

F = √(-10)² + (100)²

F = √100 + 10000

F = √10,100

F = 100.49N

Hence the net force on the object is 100.49N

A 20 kg crate initially at rest on a horizontal floor requires a 80 N horizontal force to set it in motion. Find the coefficient of static friction between the crate and the floor.​

Answers

Answer:

The coefficient of static friction between the crate and the floor is 0.41

Explanation:

Friction Force

When an object is moving and encounters friction in the air or rough surfaces, it loses acceleration and velocity because the friction force opposes motion.

The friction force when an object is moving on a horizontal surface is calculated by:

[tex]Fr=\mu N[/tex]          [1]

Where [tex]\mu[/tex] is the coefficient of static or kinetics friction and N is the normal force.

If no forces other then the weight and the normal are acting upon the y-direction, then the weight and the normal are equal in magnitude:

N = W = m.g

The crate of m=20 Kg has a weight of:

W = 20*9.8

W = 196 N

The normal force is also N=196 N

We can find the coefficient of static friction by solving [1] for [tex]\mu[/tex]:

[tex]\displaystyle \mu=\frac{Fr}{N}[/tex]

The friction force is equal to the minimum force required to start moving the object on the floor, thus Fr=80 N and:

[tex]\displaystyle \mu=\frac{80}{196}[/tex]

[tex]\mu=0.41[/tex]

The coefficient of static friction between the crate and the floor is 0.41

Which of these is an example of electrical energy being converted to mechanical energy?

Group of answer choices
Sunlight used by plants in photosynthesis
Ceiling fan
Lightning striking the ground

Answers

Answer:

Ceiling fan

Explanation:

A ceiling fan is an example of electrical energy being converted to mechanical energy.

The blades of the fan are driven by motor within the system.

Energy in a system is converted from one form to the other. Energy is neither created nor destroyed as we know from the law of conservation of energy. In this regard, the electrical energy from the outlet powers the motor. As the motor inside the fan spins, the blade in turn begins to rotate. The motion of the blade is the expression of mechanical energy.

Calculate the force used if 108J of work done is moving a wrapped present 9M

Answers

Answer:

F = 12 N

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force. It's a scalar quantity, with SI units of joules.

Being F the force vector and s the displacement vector, the work is calculated as:

W = F.s

If both the force and displacement are parallel, then we can use the equivalent scalar formula:

W=F.s

When the value of the work is known and we need to find the force, we solve the above equation for F:

[tex]\displaystyle F=\frac{W}{s}[/tex]

The wrapping present is moved by s=9 m doing W=108 J of work. The force used is:

[tex]\displaystyle F=\frac{108}{9}[/tex]

F = 12 N

A bicyclist with a mass of 50 kg is traveling at a rate of 30 m/s. It accelerates to a rate of 50 m/s in 5 seconds. What is the net force acting on the bicycle?

Answers

Answer:

200 N

Explanation:

There is only two needed factors in play here; the mass and acceleration

According to Newton's 2nd Law: F = m*a

Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2

Net force = (50 kg)(4 m/s^2) = 50*4 = 200 Newtons

What would be the formula if you
wanted to solve for the
acceleration?

Answers

Answer:

acceleration = final velocity - initial velocity / time

V-U/T

Explanation:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.
