Answer:
Velocity = 94.85m/s
Explanation:
<u>Given the following data ;</u>
Height = 1200m
Vertical distance = 1050m
To find the time, we would use the second equation of motion;
Substituting into the equation, we have;
t = 11.07 secs
To find the velocity;
Mathematically, velocity is given by the equation;
Substituting into the above equation;
Velocity = 94.85m/s
Therefore, the velocity of the water above 1050 m over the sea level is 94.85m/s.
Answer:
20 miles
Explanation:
Use pythagorean theorem
d^2 = 16^2 + 12^2
to find displacement, d = 20 miles
No, it doesn't. Weight (sometimes) indirectly affects the frictional force but not the coefficient. The frictional force is proportional the normal reaction force which often (but not always) is equal to the weight. The constant of proportionality is the coefficient of friction or its reciprocal (depending on which side of the equation the constant is on). Situations when weight and normal reaction force are unequal when they are unequal. Normal reaction force is just a force to maintain the equilibrium of the body if it can.
Explanation:
8. correct. You can get there from Maxwell's equations, a derivation that is beyond the scope of this answer.

9. Color is a property of visible light, the portion of the electromagnetic spectrum that has particular effects on the eyes and brain. Other portions of the spectrum, those observed by radio and X-ray telescopes, must be rendered in false color to make an image. The appropriate choice is the first one:
• radio telescope and X-ray telescope
