How much force (newtons) is required to accelerate a 2.55 kg remote-controlled toy car at a rate of 6.00 m/s2

Answers

Answer 1

Answer:

15.3 N

Explanation:

Force = mass x acceleration

= 2.55 kg x 6.00 m/s^2

= 15.3 kgm/s^2 = 15.3 N

Answer 2

The required force to accelerate a 2.55 kg remote-controlled toy car at a rate of 6.00 m/s^2 be 15.3 N.

What is force?

The definition of force in physics is: The push or pull on a mass-containing item changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.

Given parameters:

Mass of the remote-controlled toy car : m = 2.55 kg.

Acceleration of  the remote-controlled toy car :a =  6.00 m/s^2

Now according to Newton's 2nd law of motion,

Force = mass x acceleration

= 2.55 kg x 6.00 m/s^2

= 15.3 kgm/s^2

= 15.3 N

Hence, required force is 15.3 N.

A battery and a resistor are wired into a circuit. The resistor dissipates 0.30 W. Now two batteries, each identical to the original one, are connected in series with the resistor. What power does it dissipate?

Answers

Answer:

1.2 W

Explanation:

Let the value of resistance be R , emf of battery be E

current i = E / R

power = i² R

= E² x R / R²

= E² / R

Given

E² / R = .30

when two batteries are connected

Total emf = 2E

current = 2E / R

Power = ( 2E / R )² x R

= 4 E² / R

= 4 x .30

= 1.2 W .

If the density of water is 1000 kg/m², what is the pressure at the bottom of a swimming pool 2m
deep when it is full of water?​

Answers

Pressure = height x density x gravity = 2 x 1000 x 9.8 = 19600 Pascal ( N / m^2 )

The pressure at the bottom when the given tank is full of water will be 19600 Pa.

Pressure can be calculated by the formula,

[tex]\bold {P = \rho h g}[/tex]

Where,

P- pressure = ?

[tex]\bold {\rho}[/tex] - density of water = 1000 kg/m²

h - height of water = 2 m

g - gravity acceleration = 9.8 m/s

Put the values in the formula

[tex]\bold {P = 2 \times 1000 \times 9.8} \\\\\bold {P = 19600\ Pa}[/tex]

What effect will the following have on the inertia of a body if
(i) the force acting on it is increased.
(ii) the mass of the body is reduced.

Answers

Explanation:

Inertia is the tendency of a body to remain at rest or to do nothing.

It is the resistance to any change in position of body.

 When the force on a body increases, the inertia reduces

 When the mass is reduced the inertia reduces

According to newton's first law or the law of inertia "an object will remain in its state of rest or of uniform motion unless if it is acted upon by an external force".

Answers

Answer  888990,0 kg

Explanation:

888990,0 kg is the mass of the object.

What is Gravitational force?

Any two mass-containing objects are attracted to one another by the gravitational force. Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive.

Newton's Universal Law of Gravitation is what it is known as.

Admittedly, you aren't pushing on those other objects all that much because you don't have a very large mass. Additionally, items that are very far apart from one another do not clearly tug on one another. 

Therefore, 888990,0 kg is the mass of the object.

the internal energy of the gas increases by 114 J during the process, what is the total amount
of energy transferred as heat? Has energy been added to or removed from the refrigerant as
heat?

Answers

Answer:

Eh = 21 [J]

Removed as heat.

Explanation:

This is a case of energy conservation, we have to take into account the energies that go in and out of the system. In this case, 135 [J] of energy are entered in the form of work of the compressor to the chamber where the refrigerant is compressed, now of these 135 [J] 114 [J] were used as internal energy, this internal energy is used to increase the pressure and temperature of the refrigerant.

In this way the rest of the energy of the 135 [J] was lost in the form of heat to determine this loss of energy, we simply perform the arithmetic subtraction.

Eh = 135 - 114 = 21 [J]

Eh = 21 [J]

HELP ASAP HELP Two tennis balls of the same mass are served at different speeds: 30 m/s and 60 m/s. Which serve has more kinetic energy and by how much? Defend your answer. *

Answers

Answer:

The second ball has four times as much kinetic energy as the first ball.

Explanation:

Kinetic Energy

Is the type of energy an object has due to its state of motion. It's proportional to the square of the speed.

The equation for the kinetic energy is:

[tex]\displaystyle K=\frac{1}{2}mv^2[/tex]

Where:

m = mass of the object

v = speed at which the object moves

The kinetic energy is expressed in Joules (J)

Two tennis balls have the same mass m and are served at speeds v1=30 m/s and v2=60 m/s.

The kinetic energy of the first ball is:

[tex]\displaystyle K_1=\frac{1}{2}m\cdot 30^2[/tex]

[tex]\displaystyle K_1=\frac{1}{2}m\cdot 900[/tex]

[tex]K_1=450m[/tex]

The kinetic energy of the second ball is:

[tex]\displaystyle K_2=\frac{1}{2}m\cdot 60^2[/tex]

[tex]\displaystyle K_2=\frac{1}{2}m\cdot 3600[/tex]

[tex]K_2=1800m[/tex]

Being m the same for both balls, the second ball has more kinetic energy than the first ball.

To find out how much, we find the ratio:

[tex]\displaystyle \frac{K_2}{K_1}=\frac{1800m}{450m}[/tex]

Simplifying:

[tex]\displaystyle \frac{K_2}{K_1}=4[/tex]

The second ball has four times as much kinetic energy as the first ball.

Answer:

he second ball has four X as much kinetic energy as the first ball

Explain:

Kinetic Energy Is the type of energy an object has due to its state of motion. It's proportional to the square of the speed

m/the mass of the object

v/the speed at which the object moves

Describe Kinetic Energy.​

Answers

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

What, exactly, is moving across the medium?

Answers

Answer:

So waves are everywhere. But what makes a wave a wave? What characteristics, properties, or behaviors are shared by the phenomena that we typically characterize as being a wave? How can waves be described in a manner that allows us to understand their basic nature and qualities?

A wave can be described as a disturbance that travels through a medium from one location to another location. Consider a slinky wave as an example of a wave. When the slinky is stretched from end to end and is held at rest, it assumes a natural position known as the equilibrium or rest position. The coils of the slinky naturally assume this position, spaced equally far apart. To introduce a wave into the slinky, the first particle is displaced or moved from its equilibrium or rest position. The particle might be moved upwards or downwards, forwards or backwards; but once moved, it is returned to its original equilibrium or rest position. The act of moving the first coil of the slinky in a given direction and then returning it to its equilibrium position creates a disturbance in the slinky. We can then observe this disturbance moving through the slinky from one end to the other. If the first coil of the slinky is given a single back-and-forth vibration, then we call the observed motion of the disturbance through the slinky a slinky pulse. A pulse is a single disturbance moving through a medium from one location to another location. However, if the first coil of the slinky is continuously and periodically vibrated in a back-and-forth manner, we would observe a repeating disturbance moving within the slinky that endures over some prolonged period of time. The repeating and periodic disturbance that moves through a medium from one location to another is referred to as a wave.
