It uses electromagnetic radiation waves to enable military communications, navigation, radar, nonintrusive inspection of aircraft, and other equipment. Hope this helps.
I think there was momentum conserved
Explanation: I took the test
Answer:
mars, reason why is because they both are diff from the size
Explanation:
Answer:
20 m
Explanation:
From the equation of motion,
S = ut+1/2gt²................................. Equation 1
Where S = Height, u = initial velocity, t = time, g = acceleration due to gravity.
Note: Because the rocked is being dropped from a height, acceleration due to gravity is positive (g), and initial velocity (u) is negative
Given: t = 2.0 s, g = 10 m/s², u = 0 m/s (dropped from height)
Substituting into equation 1
S = 0(2) + 1/2(10)(2)²
S = 5(4)
S = 20 m
Hence the height of the the cliff above the pool is 20 m
Before giving you the answer straight away, I’d like to make sure you understand each option.
FIRST OPTION
“He developed the three laws of motion."
This option is not only the incorrect answer, but it is an incorrect statement. Galileo did not develop the three laws of motion. Isaac Newton was the one to compiled the three laws of motion.
SECOND OPTION
“He was the first to systematically study force and motion."
This option is a statement is true, and it could also be the correct answer. Galileo Galilei used experiments to search for the cause of motion.
THIRD OPTION
“He was the first to discover gravity."
This option is not only the incorrect answer, but it is an incorrect statement. Galileo was not the person to discover gravity. Sir Isaac Newton was the first to discover gravity.
FINAL OPTION
“He improved on Newton's laws."
This option is not only the incorrect answer, but it is an incorrect statement. Galilei did not improve Sir Isaac Newton’s laws.
Now that we’ve gone through each of the options individually, we can go ahead and determine the correct answer to the question, which is...
B ) He was the first to systematically study force and motion.
