Answer:
According to Newton's first law of motion, an object maintains its state unless a force acts on it. Therefore, a moving car does not change its direction and keeps its speed unless a force acts on it.
Using the mirror formula.
1/v + 1/u = 1/f
1/9.5 + 1/3.2 = 1/f
1/f = 3.2 + 9.5 / 9.5 * 3.2
1/f = 4.82 cm
Radius = 2f
Radius = 2 x 4.82
Radius = 9.64 cm
Answer:
The second arrow from the top to the bottom
Explanation:
This can be explained by the Newton's third law.
For every action there is an equal and opposite reaction.
When an object A exert a force to an object B. Then object B also excerts a force with the same size but opposite direction to object A.
Answer:
Erosion is the process by which natural forces move weathered rock and soil from one place to another. Gravity, running water, glaciers, waves, and wind all cause erosion. The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment.
The total resistance of a section of wire can be calculated using the equation pL/a, where “p” represents the resistivity of the material, “L” represents the length, and “a” represents the cross-sectional area. For this problem, simply substitute and simplify
Rwire = pL/a
= (2.82x10^-8)(14,000 m)/(5.9x10^-4)
= 0.6692 ohms
The resistance of this wire under these conditions would be approximately 0.67 ohms.
Hope this helps!
