The amount of heat that is required to raise the temperature of a system is calculated by the expression:
Heat required = m Cp ΔT
Heat required = 500 g (1.0 calorie/gram °C) (10.0 <span>°C)
Heat required = 5000 calorie
The correct answer from the choices listed above is the second option.</span>
Answer:
They would be at where they are for hours after.
Explanation:
Although the motion of the water is appearing to be traveling East, making Johnny think that the wave is actually pushing on the boat East bound, what is really happening here is that the motion of the particles of water is actually moving up and down that propagate to the East. Therefore, the wave would only be pushing the boat up and down, not toward land.
Hope this helps :)
When describing linear motion, you need only one graph representing each of the three terms, while projectile motion requires a graph of the x and y axes. Graphs of simple harmonic motion are sine curves. Circular motion is different from other forms of motion because the speed of the object is constant.
Answer:
A skater glides along a circular path. She defines a certain point on the circle as her origin. Later on, she passes through a point at which the distance she has traveled along the path from the origin is smaller than the magnitude of her displacement vector from the origin.
So here in circular motion of the skater we can see that the total path length of the skater is along the arc of the circle while we can say that displacement is defined as the shortest distance between initial and final position of the object.
So it is not possible in any circle that arc-length is less than the chord joining the two points on the circle
As we know that arc length is given as
length of chord is given as
so here
so we have
