Firstly let us get the time down to minutes from hours. Then the calculation will become easy.
1 hour and 45 minutes = (60 + 45) minutes
= 105 minutes
So
The distance traveled by the car in 105 minutes = 98 miles
Then
The distance traveled by the car in 60 minutes = (98/105) * 60 miles
= 5880/105 miles
= 56 miles
So the average speed of the car as can be seen from the above deduction is 56 miles per hour.
Answer:
how fast it is moving in m/s? 0.65 m/s.
Explanation:
given information:
the length of the arm, L - 0.9 m
angle, θ = 20°
First we calculate the distance in horizontal motion
s = 2 L sin θ
= 2 (0.9) sin 20°
= 0.62 m
now calculate the time
t/2 = 2π√(L/g)
t = π√(0.9/9.8)
= 0.95 s
the speed is
v = s/t
= 0.62/0.95
= 0.65 m/s
Not necessarily, object A could also be neutral, and becoming a dipole due to object B's charge. A charged object can induce a dipole in a neutral object, and that object would then become attracted without being charged.
Answer:
d = 52.20 miles
Explanation:
Given that,
Devon drove 50 miles west and then drove 15 miles north.
We need to find Devon's displacement. Let it is d. It can be calculated as follows :
Hence, Devon's displacement is 52.20 miles.
