Answer:
Option C
Explanation:
The graph shows endothermic reaction because the reactants are lower in energy and the products are higher is energy. Endothermic reactions absorb energy having products with higher energy.
C.) chemical to electrical to light
The answer to this is true. Usually when a volcano forms it starts off from the ocean floor then it will form up towards the surface. Volcanoes are also known for creating new islands like for example The Hawaiian Chain, it was created by volcanoes. in order for the islands to form, the plates in the ocean floor aka where the volcanoes are located has to push up another rock aka an island. Molten rock falls into the ocean and hardens creating a new island.
Answer:
a)5mm
b)3.3%
Explanation:
first note down the what's given
Area=
Mass of the runner=
=70kg
Fmax= 8 F (since tendon can stretch 8 times of runner's weight)
= 8 g=8 x 70 x 9.8=> 5488N
L=15cm=> 0.15m
a)
/AΔL
YAΔL=Fmax. L
ΔL=
ΔL=
=> 5mm
b) L=15cm= 150mm
Fractional change can be determined by,
(ΔL/L) *100
=
=3.33%
On Earth, the air becomes less dense and loses pressure as it rises in height. There is a bad correlation between the two variables.
<h3>What is atmosphere?</h3>
The layers of gases that envelop a planet or other celestial body are its atmosphere. About 78% of the gases in the Earth's atmosphere are nitrogen, 21% are oxygen, and 1% are other gases.
<h3>What is air pressure?</h3>
Everything you touch is pressed upon by the weighty air that surrounds you. This pressure is referred to as air pressure or atmospheric pressure. It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. A barometer is frequently used to measure atmospheric pressure.
<h3>What is altitude?</h3>
Height above sea level is how altitude is defined. Air pressure and height are two different but related ideas. In fact, they are so closely related that many airplane altimeters base their altitude calculations on air pressure. And one can also do the opposite; mountain climbers can determine whether they need to bring an oxygen supply by forecasting the air pressure on a mountaintop with a known elevation.
