Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away.
Answer:
Using no light
Explanation:
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results of that specific group.
Using no light would be the control group in this experiment because the experiment is testing the effect that light has on the growth of bean plants.
hope this helps!
The weight of an object is the force of gravity exerted on that
object and the mass of an object is the amount of matter it has, and it
stays the same wherever you are, regardless of gravity.
So, here the mass of object is 40 kg on earth,
it means it has mass of 40 kg on moon also, but when we are calculating the
weight of an object we used the following formula,
F=mg
Where F is the weight of an object in Newton
and m is the mass of object in kilogram and g is the gravity
Now here gravity on the moon is 1.6 m/s2 and m
is 40 kg
So, F = 40 x 1.6
<span>F = 64 N</span>
<span>mass of the object on moon is 40kg and weight of an object on moon is 64N.</span>
