Answer:
P = 1097 Watt
Explanation:
given,
length of stairs, L = 130 m
inclination with horizontal,θ = 30°
mass of the football player = 105 Kg
time = 61 s
we know,

Work = change in Potential energy
h = L sin 30°
h = 130 x 0.5
h = 65 m
W = m g h
W = 105 x 9.8 x 65
W = 66885 J
now,

P = 1097 Watt
hence, the power output on the way is 1097 W
Answer:
Law of multiple proportions
<h2>6300÷32.8</h2><h3>=192.07317073</h3>
<h2>6300÷33</h2><h3>=190.90909091</h3>
please mark this answer as brainlist
Potential energy = (mass) x (gravity) x (height)
1 joule = (1,000 kg) x (9.8 m/s²) x (height)
Height = 1 joule / (9,800 newtons)
= 1/9800 meter
= 0.000102 meter
= 0.102 millimeter (rounded)
The correct response is B .
