Answer:
A Bicycle
Explanation:
A Space shuttle accelerating because the Earth pulls on it through the gravitational force.
A Truck is accelerating because acceleration is necessary for an object to change direction.
A car is accelerating because it is speeding up unexpectedly?????
Answer:
1.08×10⁹ J
Explanation:
From the question given above, the following data were obtained:
Power (P) = 100 kilowatt
Time (t) = 3 hours
Energy (E) =?
Next, we shall convert 100 kilowatt to Watts. This can be obtained as follow:
1 KW = 1000 W
Therefore,
100 KW = 100 KW × 1000 W / 1 KW
100 KW = 100000 W
Thus, 100 KW is equivalent to 100000 W.
Next, we shall convert 3 hrs to second (s). This can be obtained as follow:
1 h = 3600 s
Therefore,
3 h = 3 h × 3600 s / 1 h
3 h = 10800 s
Thus, 3 h is equivalent to 10800 s.
Finally, we shall determine the amount of energy consumed as follow:
Power (P) = 100000 W
Time (t) = 10800 s
Energy (E) =?
P = E/t
100000 = E / 10800
Cross multiply
E = 100000 × 10800
E = 1.08×10⁹ J
Therefore, 1.08×10⁹ J of energy was consumed.
The natural process is called greenhouse effect. This is when the Sun's light enters the Earth, and converts to heat. Light passes through the Earth's atmosphere much easier compared to heat. Because of this, heat is trapped on Earth because it cannot exit the atmosphere as easily as light does.
Chemical change, we can't change the bread back the way it was before

Answer:

Explanation:
given,
mass of the cart 1, m₁ = 310 g
speed of car 1 , v₁ = 1.25 m/s
mass of cart 2, m₂ = 260 g
speed of cart 2, v₂ = -1.33 m/s
speed of center of mass




Hence, speed of center of mass of the system is equal to 0.0732 m/s
