Answer:
Mechanical energy
Explanation:
Mechanical energy is needed for movement of objects. Muscles convert chemical energy provided by the rest of the body to allow movement.
Answer:
The new speed of the aircraft with respect to the ground is 1414.3 mph.
Explanation:
Given that,
Angle = 37°
Velocity of jet airliner = 693 mph
Velocity of wind = 798 mph
We know that,
The new velocity of the aircraft with respect to the ground

We need to calculate the new speed of the aircraft with respect to the ground
Using formula for velocity

Put the value into the formula


Hence, The new speed of the aircraft with respect to the ground is 1414.3 mph.
<span>B. shining a bright light on the objects
and testing for decomposition </span>
<span>
In explanation, chemical property is a
characteristic of a certain substance came from an outcome due to chemical change
or reaction. In the situation above, more specifically toxicity is involved in
the chemical property/change. Hence, when the object is tested for
decomposition. Like for an example of decomposition simply in metals, rusting. Rusting
a process of degeneration of metals. Here it works the same. Toxicity is how
much damage did a certain entity do to the object. </span>
Answer:
The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn. When undoing a nut fastened to a screw by hand one realises that the amount of force required is a lot greater than when undoing the same nut using a spanner.
