PE = mass * height * 9.81
PE = 142 * 25 * 9.81
PE = 34825.5 J
Answer:
0.4 A
Explanation:
From the question,
Electric power = Voltage×current
P = VI.......................... Equation 1
Make I the subject of the equation
I = P/V..................... Equation 2
Given: P = 96 J/s, V = 230 V.
Substitute into equation 2
I = 96/230
I = 0.4 A.
Hence the current is 0.4 A
Answer: A = 0.02 m²
Explanation: Solution:
Pressure is expressed in the formula:
P = F / A where F = mg
= mg /A
= 50 kg ( 9.8 m/s²) / 25000 Pa
= 0.02 m²
Answer:
100 newton
Explanation:
newton third law of motion says to every action there is an always an equal and opposite reaction so the magnitude will stay equal but opposite direction
Answer: angle of incidence
