The acceleration due to gravity on the moon is 1. 6 m/s2, about a sixth that of Earth’s. Which accurately describes the weight o
snow_tiger [21]

Weight is the force applied on the planet by its mass. The weight of an object is 6 times lighter than that of the earth. Option C is correct.

What is Wight?

  • It is the product of the mass and the gravitational acceleration.
  • Weight is the force applied on the planet by its mass.

The formula of weight is,

w = mg

Where,

w- weight

m - mass

g- gravitational acceleration

In the question given here the gravitational acceleration of the moon is 6 times less than that of the earth.

Therefore, the weight of an object is 6 times lighter than that of the earth.

Mila [183]

Answer:

a. Picture attached

b. V, X

c. t=0.12 s

d. It makes sense cosidering that a normal heart beat rate is between 60 and 100 beats per minute (bpm).

Explanation:

First we have to identify the unknown of this problem:

a: acceleration\\t: time

Considering the characteristics of the problem and that distance and velocity are specified, the acceleration is constant, for that reason we use the equations of uniformly accelerated motion as follows:

v=v_{0}+at\\ x=x_{0}+ v_{0}+\frac{1}{2}at^{2}

If we reorganize the equations, considering that x_{0} and v_{0} are zero because motion starts from rest , we have:

a=\frac{v}{t} \\x=\frac{1}{2}at^{2}  =\frac{1}{2}\frac{v}{t} t^{2}=\frac{1}{2} vt\\t=\frac{2x}{v} \\t=\frac{2*1.80cm}{30.0\frac{cm}{s} } \\t=0.12 s

Finally, the analysis of the result leaves us to understand why the normal heart beat rate varies between 60 and 100 bpm.
