<span>Some geographic areas endure cycles between these two processes called transgressive-regressive sequences. The rocks of western Pennsylvania are one example. Sandy beaches often leave observable records of transgression by covering marsh sediments that were once behind it as it moves inland. The original sediments are then covered by even deeper water sediments, which geologists can trace and record. It is generally believed that transgression will increase in accordance with rising sea levels worldwide</span>
25/1500 is equal to 0.8/x
0.8*1500 is equal to 1200
1200/25 is equal to 48 N
Answer:
50 W
Explanation:
Case 1
Power = V * I
100 = 220 * I
I = 
A
Case 2
P = V * I
P = 110 *
P = 50 W
I think the answer is 50 W
Hope it helps
Answer:
1.9 MPa
Explanation:
Mass of person = 81 kg
Mass of chair = 3.8 kg
Diameter of contact point = 1.2 cm = D
Radius of contact point = 1.2/2 = 0.6 cm
Total mass of chair and person = 81 + 3.8 = 84.8 kg = M
Acceleration due to gravity = 9.81 m/s²
Force acting on the floor
<em>F = Mg</em>
<em>⇒F = 84.8×9.81</em>
<em>⇒F = 831.888 N</em>
Area of the contact point
<em>A = πR²</em>
<em>⇒A = π0.006²</em>
<em>⇒A = π0.000036 m²</em>
Area of the four points is
<em>4A = 0.000144π m²</em>
Pressure
Pressure exerted on the floor by each leg of the chair is 1.9 MPa
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.
