Answer:

Fales

Explanation:

That's why scientists and engineers often measure an object's mass—how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.

Answer:

60Nm

Explanation:

Given data

Applied force= 200N

length of spanner= 30cm to meter

= 30/100= 0.3m

We know that the formula for the moment is

P=Fl

that is

P= force * length

P= 200*0.3

P= 60Nm

Hence the moment is 60Nm

Explanation:

The motion of gas molecules in the air in the tyre will speed up.

Molecular motion is defined as the movement of molecules in a certain direction. The molecular motions are affected by heat and temperature. This is because the temperature is the measurement of the average kinetic energy of the molecules and represents the motion of molecules.

The kinetic energy of an object is the energy which it possesses due to its motion. It gives the work needed to accelerate a body of a given mass from rest to its stated velocity. To calculate kinetic energy

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

Kinetic energy depends on the velocity of the object which means that when the velocity of an object doubles, its kinetic energy quadruples.

Kinetic energy must always be either zero or a positive value.

Kinetic energy is not a vector.

The gas molecules inside the tyre exert pressure on the walls of the tyre as the molecules collide with the walls of the tyre.

When the air in the tyre becomes hotter, the pressure rises as more collisions.

The pressure in the tyre increases as there will be more frequent collisions with the tyre wall.

Answer:

Nervous system messages travel through neurons as electrical signals. When these signals reach the end of a neuron, they stimulate the release of chemicals called neurotransmitters. Neurotransmitters travel across synapses, spaces between neurons or between neurons and other body tissues and cells.

Answer:

1.2 mph

Explanation:

14.4 ÷ 12 = 1.2

Answer: -110N

Explanation:

Assign a variable x to the unknown force. The net force was given as +25N, which means the sum of the two forces must equal +25N.

Subtract 135N on both sides

135 + x = 25

x = -110N

The negative sign indicates direction because force is a vector.

Answer:

Electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. An electric field can be produced also by a changing magnetic field.

========================================

Work Shown:

To find the momentum, we multiply the mass and the velocity.

m = mass = 1500 kg

v = velocity = 3 m/s

p = momentum

p = m*v

p = (1500 kg)*(3 m/s)

p = (1500*3) kg m/s

p = 4500 kg m/s

The momentum of an object is the product of its mass and velocity. Thus momentum of the car with 1500 kg and velocity of 3 m/s is 4500  kg m/s.

Momentum is a physical quantity that measure the ability to keep the force which make an object moves faster. Momentum like force is a vector quantity and is characterized with magnitude and direction.

Momentum is the product of velocity and its mass. Hence as the mass or velocity increases, momentum also increases. Increase in momentum makes the object moves faster.

Given mass of car = 1500 Kg

velocity = 3 m/s

momentum = velocity × mass

= 1500 Kg × 3 m/s

= 4500 Kg m/s.

Therefore, the momentum of the car is 4500 kg m/s.

Answer:

the distance between Kerala and Karnataka is 425 km.

Explanation:

Given;

speed of the train, u = 85 km/h

time taken for the train to travel from Kerala to Karnataka, t = 5 hours

The distance between Kerala and Karnataka is calculated as;

Distance = speed x time

Distance = 85 km/h  x  5 h

Distance = 425 km

Therefore, the distance between Kerala and Karnataka is 425 km.

If you have a strong enough magnetic field all matter is magnetic. But copper is so weakly magnetic that we can't observe it without very, very large magnetic fields. So the short answer is "No, copper isn't magnetic." This can quickly be tested by trying to pick up a penny with a magnet.

Answer:

Speed changes at the rate of 24 m/s for each second over time.

Explanation:

We are told the object's acceleration is equal to 24 m/s²

Now we know that acceleration can also be defined as the rate of change of speed with time. Also speed has a unit known as m/s.

Thus, we can rephrase the acceleration in this question to mean;

Speed changes at the rate of 24 m/s for every second with time.
