Answer:
4.2 is the answer
Explanation
The image formed in a plane mirror is an equal distance behind the mirror as the object in front of it.
Step 1: the equation to this problem would be: 8.4/2
Step 2: 8.4 ÷ 2 = 4.2
Answer:
wavelength.
Explanation:
One complete expression of a waveform beginning at a certain point, progressing through the zero line to the wave’s highest (crest) and lowest (trough) points, and returning to the same value as the starting point is called a is called wavelength. Its can be also defined as the distance between two successive crests or trough points in wave form.
Answer:
The force exerted by the ball on the bat has a magnitude of 100 N and its direction is exactly opposite to that of the force exerted by the bat on the ball.
Explanation:
Recall that Newton's third law tells us that : "For every action, there is an equal and opposite reaction."
Therefore if the bat acts on the ball with a force of 100 N, the ball acts on the bat with a similar magnitude of force (100 N) but direction opposite to the original force.
I believe the answer that you're looking for is temperature probe. As you raise the heat of the metal cylinder by a specific, measured number of degrees Celsius, you also record the amount of energy put out by the heat source. Specific heat of a substance is equal to the amount of energy or heat needed to raise a substance by one degree Celsius. Use the equation Q=cmΔT, where Q is heat/energy added, c is the specific heat, m is the mass of the cylinder, and ΔT is the change in temperature of the cylinder.
