Here
is the change in voltage while triangle x is the change in x

Answer:
asdccccccccccf give me my points
Explanation:
Grav Force = GMm/r squared. M is earth's mass. m is the probe. r is distance to centre of earth.Given that 600 = GMm/(10,000^2).GMm = 600x(10,000^2) for 10, 000 milesGMm = ? x (20,000^2) for 20, 000 milestherefore600x(10,000^2)=? x (20,000^2)therefore [600x(10,000^2)]/(20,000^2)=? [600x(1x1)]/(2x2)=? [600/4]=? ?=150lb.Same procedure for b and c.Please ask if you want further help.
Answer: 0.14 Hz
Explanation:
We are told the person counts 10 waves in 68 s, from this information we can calculate the frequency
, which is defined as the number of oscilations or waves per unit of time. Then:


This is the frequency of the ocean waves. Now, according to the International System of Units (SI), frequency is measured in Hertz (
), which is equivalent to
.
So, according to this, the frequency of the ocean waves is 
here since string is attached with a mass of 2 kg
so here tension force in the rope is given as

here we will have

now we will have speed of wave given as

here we will have


now we know that frequency is given as
F = 100 Hz
now wavelength is given as


so wavelength will be 0.16 m
