What is the average speed of a car that traveled 300.0 miles in 5.5 hours?
Answers
The average speed of will be "0.41 m/s".
Speed and Distance:
According to the question,
Distance = 300.0 miles
Time = 5.5 hours
We know,
miles =
meters
Now,
By converting 5.5 hours into seconds, we get
=
=
hence,
The speed will be:
=
= or,
Thus the above answer is right.

Answer:
54.54 miles per hour
Explanation:
You do 300 divided by 5.50 to get 54.545454 but you can estimate it to be about 54.54 miles per hour.
So, top average speed of car was 54.54 mph.

Air from the equator moves toward the poles slower than the ground below it, so friction causes the air to veer east. In contrast, air from the poles moves toward the equator faster than the ground below it, so friction causes it to veer to the west.

Answer:
The displacement of the particle after a time of 3.64 × 10⁻² s = 0.366 m
Explanation:
Given q = 19.6 μC = 19.6 × 10^-6 C
m = mass of the charge = 2.37 × 10^-5 kg
E = 668 N/C
We first calculate the force on the charge
F = Electric field × Charge = Eq = 668 × 19.6 × 10⁻⁶ = 0.0131 N
Then, using Newton's law of motion's F = ma
We can obtain the acceleration of the particle
0.0131 = 2.37 × 10⁻⁵ × a
a = 0.0131/(2.37 × 10⁻⁵) = 552.4 m/s²
Then, using the equations of motion, we can obtain the displacement of the charge after t = 3.64 × 10⁻² = 0.0364 s
u = initial velocity = 0 m/s (since the particle was initially at rest)
t = 0.0364 s
a = 552.4 m/s²
d = displacement of the particle = ?
d = ut + at²/2
d = (0)(0.0364) + (552.4)(0.0364²)/2 = 0 + 0.366 = 0.366 m

Answer:
Big Bang theory
Explanation:
The big bang theory describes the beginning of the universe. According this theory, all the matter of the universe was confined at a point and about 15-20 billion years ago, it started expanding out of a huge explosion -the big bang. The universe has been expanding since then. The discovery of cosmic microwave background radiation provides the evidence to this theory.
Thus, the correct option is C.
