Answer:
C. 900J (i tried my best)
Explanation:
the student's mass=60kg
gravitational field strength= 10N/kg:
1kg = 10N
60kg = 600N
(where 600N is the gravitational field strength of the student)
√1.5²+2² (pythagoras theorem)
=2.5m (the stairs' length)
work done= N x distance move in the direction of force (m)
=600N x 2.5m
=1500J @ Nm
1500J - 600N (gravitational field strength of the student)
=900J(??)
-correct me if i'm wrong i'm just a human :)

Answer:
the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring
Answer:
Amplitude
Explanation:
The amplitude is maximum height a wave is measured from its rest position.
The precision of the measuring instruments will be 2.5%.
<h3>What is precision?</h3>
It should be noted that precision simply means how close a test result will be when it's repeated.
In this case, the precision of the measuring instruments will be:
= (2 - 1.95)/2.
= 0.05/2
= 2.5%
Therefore, the the precision of the measuring instruments will be 2.5%.
