Answer:
Zero, the support force and gravitational force together equal a zero net force
Explanation:
<span>A hypothesis is testable when you can create an experiment to study the proposition contained within the hypothesis. For example, the hypothesis ‘Santa travels slower than a unicorn’ is testable in theory by measuring the speeds of both, but it is not truly testable because neither exists in reality.</span>
PE = mgh
Mass, m = 7kg, g ≈ 10 m/s², height = 2m
= 7*10*2
= 140 Joules.
Answer:
<h2>6000 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 2000 × 3
We have the final answer as
<h3>6000 kg.m/s</h3>
Hope this helps you
Answer:
A. velocity has a direction .. .
with magnitude too but speed has only magnitude
