Answer:
The answer to your question is: c = 353 mi/h; Ф = 7.3°
Explanation:
You can see the picture below
To solve this problem, just imagine a right rectangle which the legs is 350 mi/h and 45 mi/h and we are going to find the hypotenuse.
c² = a² + b²
c² = 350² + 45²
c² = 122500 + 2025
c² = 124525
c = 352.9 ≈ 353 mi/h
tanФ = 45/ 350
tan Ф = 0.12
Ф = 7.3°
Answer:
option C
Explanation:
given,
height of the hammer, h = 2 m
acceleration due to gravity of the moon, g = 1.62 m/s²
time taken by the hammer to reach at bottom = ?
initial speed of the hammer, u = 0 m/s
using equation of motion for the time calculation
t² = 2.469
t = 1.57 s ≅ 1.6 s
hence, the time taken by the hammer to reach the bottom is equal to 1.6 s.
The correct answer is option C
It depends on the angle of the earth, and our point of view. A full moon would occur if we were to be right in front of it.

Explanation:
Oil keeps the moving metal parts of an engine smoothly rubbing together through lubrication. Just like with other mechanical devices, energy can be lost due to friction caused by lack of proper lubrication. When an engine is running on old or insufficient oil, more friction and heat is produced between the rubbing moving parts. A decline in gas mileage follows this since the fuel takes more than usual to do the same task.
