You pull a wagon with a force of 20 N. The wagon has a mass of 10 kg. What is the wagon's acceleration?
Nana76 [90]

Answer:

<h3>The answer is 2 m/s²</h3>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

where

f is the force

m is the mass

From the question

f = 20 N

m = 10 kg

We have

a =  \frac{20}{10}  \\

We have the final answer as

<h3>2 m/s²</h3>

Hope this helps you

What is equivalent resistance? How do you calculate it for a series circuit?
Annette [7]

FORMULA:

R(s) = R1 + R2 + R3 + Rn where n is the number of resistors.

ANSWER:

The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated.

We already know that, In series combination all the resistors are connected directly. So, to calculate the equivalent resistance in series we just have to add the all value of resistance.
