What is a unit of acceleration? a. m/s b. m/s2 c. m2/s d. kg-m/s2

1 answer:

3 0

A). m/s ... meters per second.
   That's a speed.

b). m/s² ... (meters per second) per second.
   Acceleration.

c). m²/s ... square meters per second.
   Rate of change of area.
   Meaningless unit, unless you happen to be
   a painter of houses or a mower of lawns.

d). kg-m/s² ... (mass) x (an acceleration).
      This is a unit of force.
   In fact, it's the definition of "newton".

Calculate the volume of this regular solid.

Nataly [62]

Answer:

V = 42.41cm^3

Explanation:

In order to calculate the volume of the solid, you use the following formula:

$V=\frac{1}{3}\pi r^2 h$

where

r: radius of the circular base of the cone = 3 cm

h: height from the circular base to the peak of the cone = 4.5 cm

You replace the values of r and h in the formula for the volume V:

$V=\frac{1}{3}\pi(3cm)^2(4.5)=42.411cm^3\approx42.41cm^3$

hence, the volume of the solid is 42.41 cm^3

If constants aren't given in an experiment, what can be constant in the experiment?

mario62 [17]

Answer:

Anything in an experiment that remains unchanged.

Explanation:

An example could be the temperature of the laboratory room. If there is something that has an effect on an experiment that is not variable, it is a constant. Another constant could be, say, if you were doing calculations with the same amount and kind of fluid throughout the experiment, then that fluid would also be a constant.
