My car engine can generate 3000 Newtons of force and the car masses 1500 kg. How fast can the sports car accelerate?​

Physics
1 answer:
xeze [42]2 years ago

Answer:

The sports Car can accelerate at 2 m/s².

Explanation:

Force:

Force is the push or pull on an object with mass that causes it to change velocity or to accelerate.

Force represents as a vector, which means it has both magnitude and direction.

Given:

Mass of car = 1500 kg

Force           = 3000 Newtons

To Find:

Acceleration, = ?

Solution:

Formula:

Force = Mass\times Acceleration\\F= ma\\3000 = 1500\times Acceleration\\Acceleration = \frac{3000}{1500} \\Acceleration = 2\ m/s^{2}

Therefore, the sports Car can accelerate at 2 m/s².

1. What is wave motion
nadya68 [22]
A wave is basically propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.

How does earths magnetic field protect us from solar flares
Alex787 [66]

Answer:

Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation.

From laboratory measurements, we know that a particular spectral line formed by hydrogen appears at a wavelength of 486.1 nanome
aksik [14]

Answer:

The star is moving toward us

Explanation:

The wavelength of a distant object changes due to the change in the distance between the observer and the object. This is known as the Doppler effect.

If the wavelength decreases this means that the wavelength in going towards blue which is shorter wavelength. This is known as blue shift. If blue shift occurs then it means that the object is coming closer to the observer.

Hence, the star described here has blue shifted and is moving closer to us.

A balloon is charged until it has a voltage of v=9800V. A student reaches out and is shocked by a spark. The electric force does
alina1380 [7]

a)]An expression for the magnitude of charge transferred Q is Q = W/V.

b) The magnitude of the charge, in coulombs is  1.02 x 10⁻⁹ Coulomb.

c) Number of electrons in this are 63.75 x 10⁸ electrons.

<h3>What are electrons?</h3>

The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.

A balloon is charged until it has a voltage of v=9800V. A student reaches out and is shocked by a spark. The electric force does W= 1x10⁻⁶ J of work transferring the charge.

a) Work done = Charge x potential

W = Q x V

Q = W/V

b)Substitute the values into the expression, we have

|Q| =  1x10⁻⁶/9800

|Q| =  1.02 x 10⁻⁹ Coulomb

c) No of electrons  = total charge /charge on electron

n = 1.02 x 10⁻⁹/1.6 x 10⁻¹⁹

n = 63.75 x 10⁸ electrons
