Penn Foster Students: Light can pass through Object B faster than it can pass through Object A
Answer:
Average force exerted by the water on the blades is 1024 N
Explanation:
As we know that the force due to water jet is given by
here we know that
so here we will have
Average force exerted by the water on the blades is 1024 N
Answer:
Explanation:
From the exercise we know that the force on the plane is 7934N upward at an angle of 54.2º.
If analyze the forces in the vertical direction, the acceleration is zero because the plane is moving with constant velocity
∑
So, the <u><em>weight of the plane</em></u> is 6435N
B. a covalent bond because a covalent bond is when 2 atoms share either 1 or more than 1 pairs of electrons, and valence electrons are the type of electrons that are shared in a covalent bond.
1). an electric motor running
Electrical energy is changing into kinetic energy and a little bit of heat
2). light a match
The chemical energy stored in the match head changes into light and heat energy.
3). a light bulb
Electrical energy is changed into light and heat energy.
