Gravity is pulling everything down . Without it, we all would be floating.
Answer:
P-value of the test statistic is 2.499
Explanation:
given data:
size sample is 24
sample mean is 414 gm
standard deviation is 15
Null hypotheis is


level of significance is 0.01
from test statics

degree od freedom is = n -1
df = 24 -1 = 13

t = -1.959
from t table critical value of t at 0.1 significane level and 23 degree of freedom is 2.499
Answer:
4.096 kW
Explanation:
Applying,
P = Fvcos∅................. Equation 1
Where P = Power of the motor, F = Force exerted on the motor, v = Velocity, ∅ = angle.
From the question,
Given: F = 500 N, v = 10 m/s, ∅ = 35°
Substitute these values into equation 1
P = 500×10×cos35°
P = 4095.8 W
P = 4.096 kW
Hence the power rating of the moto in kW is 4.096 kW
