What average net force is required to stop a 1950 kg car in 10.5 s if it’s initially traveling at 28m/s

Answer:

[tex]\boxed {\boxed {\sf 50,000 \ Newtons }}[/tex]

Explanation:

Force can be found by multiplying the mass by the acceleration.

[tex]F=m*a[/tex]

The mass of the car is 5,000 kilograms and it's acceleration is 10 meters per square second.

[tex]m= 5,000 \ kg \\a= 10 \ m/s^2[/tex]

Substitute the values into the formula.

[tex]F= 5,000 \ kg * 10 \ m/s^2[/tex]

Multiply.

[tex]F= 50,000 \ kg*m/s^2[/tex]

[tex]F= 50,000 \ N[/tex]

A net force of 50,000 Newtons is required to accelerate a 5,000 kilogram car at 10 meters per square second.

Answer:

Maximum compression distance (x) = 2.236 m (Approx)

Explanation:

Given:

Weight of frog = 4,000 N

Height = 5 m

Constant force = 8,000 N/m

Frictional force = 1,000 N

Find:

Maximum compression distance (x)

Computation:

Using Law of conservation;

mgh = 1/2(k)(x)²

4,000(5) = 1/2(8,000)(x)²

Maximum compression distance (x) = 2.236 m (Approx)

Matter is a substance which has mass and takes up space by volume the properties of matter are,

States of matter (solid,liquid,gas)are inter convertable.

Force of attraction varies from one kind of matter to another.

States of matter can be varied by varying temperature and pressure.

Answer:

80g

Explanation:

The half - life is the time taken for half of radioactive substance to decay to half of its original composition.

After 4 half lives, the carbon - 14 sample is 10grams

 Now let us trace the decay of this substance;

At the 3rd  half life, it will have double the amount at the 4th half life;

                 2 x 10  = 20g

At the 2nd half life, there will be double the amount at the 3rd half life;

                20 x 2  = 40g

Originally, we are going to have;

               40 x 2 = 80g

Answer:

B

Explanation:

Answer:

Doubling the mass of both objects

Explanation:

If you double the mass of both objects, the gravitational force will quadruple, if you move the objects away from each other, the gravitational force will decrease

The gravitational force of attraction is increased by doubling the mass of both objects.

According Newton's law of Universal gravitation force, two objects in the universe attracts each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of distance between them.

[tex]F = \frac{Gm_1 m_2}{R^2}[/tex]

where;

Thus, we can conclude that by doubling the mass of both objects or reducing the distance between them, the gravitational force of attraction increases.

Explanation:

Step one:

given data

length of rod r= 2.25m

Required torque = 11 Nm

Required

The force needed to produce a torque of 11Nm

Step two:

"By definition, Torque is the twisting force that tends to cause rotation.

The point where the object rotates is known as the axis of rotation."

Mathematically,

[tex]\tau = rF\sin\theta[/tex]

[tex]\tau[/tex] = torque

r = radius

F = force

[tex]\theta[/tex] = angle between F and the lever arm

in this case is zero

[tex]\tau = rF\\\\F=\tau/r[/tex]

substituting we have

F=11/2.25

F=4.88N

F=4.9N approx.

Answer:

it right. Its The Iron Nail i just did it and i got correct  (:

Explanation:

The core of the electromagnet if In an electromagnet that is made up of a D-cell battery with wire wrapped around an iron nail, the ends of the wire being taped to the battery is iron nail so, option D is correct.

A coil surrounding a magnetic core through which an electric current is conducted to magnetize the core is an electromagnet. Wherever controlled magnets are needed, such as in devices where the magnetic flux needs to be adjusted, reversed, or turned on and off, an electromagnet is utilized.

The idea of the magnetic circuit systematizes the engineering design of electromagnets. The ampere-turns of the coil that creates the magnetic field and magnetic flux in the magnetic circuit are known as the magneto motive force F, or Fm, in this context.

Thus, the core is an iron nail.
