Surrounding a magnet is a magnetic field. Surrounding an electron is an electric field. Surrounding Earth is
trasher [3.6K]

Answer: B. A gravitational field

Explanation:

Surrounding earth is gravitational field. Gravitational field is a region of space were gravitational force can be felt and gravitational force is the gravitational pull on the surface of the earth. The presence of this gravity is what allow us to be able to walk freely without falling. It also make us jump up and be able to land back on the ground. Assuming there are no force of gravity in the surface of the earth, there won't be any possibility of landing back on the ground after jumping.

A temperature of a 0.349 kg sample of copper decreases from 87.0 °C to 21.0 °C. How much heat
Arte-miy333 [17]

We have that heat flow out of the copper sample  is mathematically given as

Q=8.86809J

<h3> Heat flow</h3>

Question Parameters

  • A temperature of a 0.349 kg sample of copper
  • decreases from 87.0 °C to 21.0 °C.

Endothermic Reaction

It is common knowledge that an endothermic reaction is one where the system absorbs heat energy from the <em>environs</em>.

Exothermic Reaction

An exothermic reaction is one where the system releases heat energy to the <em>environs</em>.

Generally the equation for Heat   is mathematically given as

Q=mCdt\\\\Therefore\\\\Q=0.349*0.385*(87-21)

Q=8.86809J

A person is hauling their taco stand and it takes 3,500 Joules of work to stop the taco stand. What force was exerted on the tac
Lapatulllka [165]

Given the work done, the force exerted on the taco stand through the given distance is 2.3 × 10³ Newtons.

<h3>What is Work done?</h3>

Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;

W = f × d

Where f is force applied and d is distance travelled.

Given that;

  • Work done W = 3500J = 3500kgm²/s²
  • Distance covered d = 1.5m
  • Force applied F = ?

W = f × d

3500kgm²/s² = f × 1.5m

f = 3500kgm²/s² ÷ 1.5m

f = 2.3 × 10³ kgm/s²

f = 2.3 × 10³ N

Given the work done, the force exerted on the taco stand through the given distance is 2.3 × 10³ Newtons.
