-- We know that the Earth is a spinning globe.
-- We know what the weather will be like in your town tomorrow.
-- We know the distance from us to the Sun and the Moon.
-- Best of all: Your doctor can give you shots so you won't get flu,
chicken pox, measles, mumps, whooping cough, tetanus, diphtheria,
smallpox, or polio.
Almost EVERY kid used to get chicken pox, measles, and mumps
when I was in school, and thousands of kids used to die every year
from diphtheria and polio. And now, you probably never heard of
most of these.
Answer:
5 miles
Explanation:
the bus is going 60km/hour meaning its going a mile a minute and it went on for 5 minutes meaning it went for 5 minutes/
Answer:
When we say that an object moving in the +x axis experiences an acceleration of 2.0 m/sec2, it really means the object is increasing its velocity by 2.0 m/s in every second.
Explanation:
As we know that Acceleration is the rate of change of velocity with respect to time, in terms of both speed and direction.
i.e.
a = Δv/Δt
so when we say that an object moving in the +x axis experiences an acceleration of 2.0 m/sec2, it really means the object is increasing its velocity by 2.0 m/s in every second.
Hi there!
We can use the following equation for constant velocity:
d = displacement (m)
v = velocity (m/s)
t = time (s)
Plug in the givens:
Answer:
The average emf induced in the coil is 175 mV
Explanation:
Given;
number of turns of the coil, N = 1060 turns
diameter of the coil, d = 20.0 cm = 0.2 m
magnitude of the magnetic field, B = 5.25 x 10⁻⁵ T
duration of change in field, t = 10 ms = 10 x 10⁻³ s
The average emf induced in the coil is given by;
where;
A is the area of the coil
A = πr²
r is the radius of the coil = 0.2 /2 = 0.1 m
A = π(0.1)² = 0.03142 m²
Therefore, the average emf induced in the coil is 175 mV
