Answer:
mass (m) is 5 kg
acceleration due to gravity (g) is 9.8 or 10 m/s2
weight (w)is ?
w= mg
w=5×10
=50 N
hence weight is 50 N
Answer:
a.
Explanation:
It decreases from the aorta to the vena cava.
Answer:
Vitamins and minerals are considered essential nutrients—because acting in concert, they perform hundreds of roles in the body. They help shore up bones, heal wounds, and bolster your immune system. They also convert food into energy, and repair cellular damage.
Walking to the dining room for their meal amplifies Trudy body's metabolism which leads to better burn up of calories once they consume and digest their food.
Answer:
True
Explanation:
<u>Rotational and linear motions are analogous to each other.</u>
<u>The inertia of a body in a linear motion is its mass.</u> This can be seen from Newton's second law of thermodynamics:
F = ma
The larger the value of the force, the larger the inertia is (m) and the slower it accelerates.
<u>The inertia of a body in a rotational body is it moment of inertia (I).</u> Both I and m are same but I depends on both the shape and mass of the rotating body.
For example, The inertia of a solid disk with mass M and radius R is:

Hence, the statement is true.
