Students hypothesized that by running an electric current through the wire of the apparatus shown here, they could cause a non-m
agnetic nail to exhibit magnetic properties. What would be a reasonable way to test this?
a
Question 7 options:
a.Weigh the nail first while before turning the current on and again while the current was on.
b.Put the nail in water before turning the current on and again after turning the current off.
c.Examine the nail under a microscope before turning the current on and again after turning the current off.
d.See if iron filings will stick to the nail before turning the current on and again while the current was on.

Answer:
1.243 mph
Explanation:
initial velocity of the car given as
final velocity is given as
as we know that
now we can convert final speed into m/s
now acceleration is rate of change in velocity
so the acceleration of the car is 3 m/s^2
Answer:
Accuracy measures how close results are to the true or known value. Precision, on the other hand, measures how close results are to one another.
Answer:
8.829 m/s²
Explanation:
M = Mass of Earth
m = Mass of Exoplanet
= Acceleration due to gravity on Earth = 9.81 m/s²
g = Acceleration due to gravity on Exoplanet
Dividing the equations we get
Acceleration due to gravity on the surface of the Exoplanet is 8.829 m/s²
Ratio
L nobody cares and bozo
