A 4800 Watt heater is supposed to be plugged into a 120 volt outlet to work correctly. If the heater was plugged into a 90 volt source instead, the amount of heat produced would
Answer:
3600
Explanation:
90 of 120 is 3/4 so 4800 - 1200 is 3600.

What is the wavelength?
A car has a mass of 2,000 kg and is traveling at 28m/s. What is the car’s kinetic energy?
984,000 J
784,000 J
484,000 J
Answer:
784,000 J
Explanation:
For this question we can simply use the equation for the Kinetic Energy which is : [tex]\frac{1}{2} mv^2[/tex], where m = the mass and v = the velocity.
So let's put the values given into the equation.
[tex]K.E = \frac{1}{2} *2000*(28)^2 = 784000 J[/tex]
The car's kinetic energy is 784,000 Joules

Newton's First Law state
For every action there is an equal and opposite reaction.
An object in motion stays in motion unless acted upon by an unbalanced force.
Gravity acts on all objects that have mass.
Force= mass x acceleration
Answer: an object in motion stays in motion unless acted upon by an unbalanced force
Explanation: this is Newton’s first law of motion, which states that an object, whether in a moving or resting state, will continue to stay in that state unless there is an unbalanced force that changes that state. For a moving object, an example would be friction worth the ground. For a resting object, an example would be the force of a push.

Tidal energy is alternative source of energy. give reason
Answer:
Tidal energy is alternative source of energy because the energy it produces is free and clean as no fuel is needed and no waste bi-products are produced. It has the potential to produce a great deal of free and green energy.

Explanation:
What is role of force on the speed of moving object?
Explanation:
this is the ans hope it works
Answer:
Forces make things speed up (or accelerate). When a force pushes or pulls the object, the object will move in the direction of the force. The bigger the force, and the lighter the object, the greater the acceleration.
Explanation:
The action from a force can cause an object to move or speed up (accelerate), to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it can be said that a force on an object results in the acceleration of an object.
A simple mathematical relationship exists between the mass of an object (m), the net force on the object (f) and its acceleration (a). The acceleration of an object is directly proportional to the net force and indirectly proportional to the object’s mass (a = f/m).
