Answer:
Explanation:
Let the forward displacement is taken is positive, and the backward displacement is taken is negative.
first displacement = + 18 cm
second displacement = - 6 cm
third displacement = - 12 cm
net displacement = 18 - 12 - 6 = 0 cm
Answer:
42.9 μF
Explanation:
V = 3.50 V, Q = 150 μC
C = Q/V = 150/3.50 μF = 42.9 μF
Answer:
1) Skid
2)<u> </u>Rocking
3) Oversteer situation
4) Controlled breaking
5) Overdriving headlights
6) Hydroplaning
7) Understeer situation
Explanation:
1) A <u>skid</u> results when a vehicle loses part or all of its grip on the road
2)<u> Rocking</u> is a technique that can be applied when trying to move your vehicle out of deep snow
3) The action of vehicle's rear end sliding out to a side is called an <u>oversteer situation</u>
4) <u>Controlled breaking</u> is a technique of reducing your speed as quick as possible while maintaining control of your vehicle
5) Driving at a speed where the stopping distance of your vehicle is longer than the distance you can see with your headlights is called <u>overdriving headlights</u>
6) <u>Hydroplaning</u> occurs when a tire loses road surface contact and rises on top of water
7) It is an <u>understeer situation</u> when your front tires begin to plow and your vehicle is not responding or not responding as quickly as it should, to a steering point
Answer:
The acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg is 3.2 m/s².
Explanation:
Given
To determine
Acceleration a = ?
Important Tip:
- The acceleration of a boat can be found using the formula F = ma
Using the formula
where
- a is the acceleration (m/s²)
now substituting F = 4000, m = 1240 in the formula
Switch sides
Divide both sides by 1240
Simplify
m/s²
Therefore, the acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg is 3.2 m/s².
Newton's universal law of gravitation says that the force acting upon (and therefore the acceleration of) an object toward Earth should be inversely proportional to the square of its distance from the center of Earth.
