Answer: C. 1.64 x 10-3 m/s2
Your answer is B, a long time ago the continents that we know today used to be all one continent and was separated years ago due to earthquakes long ago. I think that's how it happend, but I am 100% sure its B
<u>Answer
</u>
D. Salt water is denser than freshwater.
<u>Explanation</u>
A boat is able to float on water because it experiences an upthrust upwards.
The magnitude of the upthrust depends on the density of the liquid.
When the liquid is denser the boat will experience a great upthrust as compared to when in a less dense liquid.
If the boat sinks lower in the freshwater than in salty water, then Salt water is more dense than freshwater.
Answer:
Explanation:
angular frequency of resulting SHM ω = √(k/m
ω =√(100x32/1
ω = 56.57
Period T
ω = 2π /T = 56.57
T = 2π / 56.57
= .11 s .
spring is stretched by 1 inch so it will become the amplitude of frequency
A = 1 inch
when t = 0 , x ( displacement ) = A = 1 inch
equation of motion
x ( t ) in inch = A cosω t
= 1 cos 56.57t
x ( t ) in inch = 1 cos 56.57 t .
Electric force is typically weaker than gravitation force.
