Average speed of the car is 11 m/s
Explanation:
- Speed is calculated by the rate of change of displacement.
- It is given by the formula, Speed = Distance/Time
- Here, distance = 2155 m and time = 195.9 s
Speed of the car = 2155/195.9 = 11 m/s
It's the angle made by the incident ray when it's perpendicular to the surface. (Perpendicular lines are the lines that form a graph or like a 90-degree angle)
There are no probably-true statements on the list of choices that you provided.
No it isn't. That's a description of a generator.
Substance Y has more atoms per gram than substance W.
Explanation:
The best conclusion supported by the data suggests that substance Y has more atoms per gram compared to substance W:
Chart;
2.542 W
0.900 X
3.209 Y
1.657 Z
From the chart above see that Y has more specific heat W. This implies that Y will require more energy to raise the temperature of the substance compared to W.
Specific heat is the amount of heat required to raise the temperature of 1g of a substance by 1K.
The more the amount of matter per gram present, the more the specific heat it will have.
