Answer:
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. "If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance

c. By using the Select Data button and the Select Data Source optionExplanation:A scatter plot is a plot which is used to plot the points of the data on the horizontal and the vertical axis also it depicts how one variable is affected by the another. After preparing the scatter plot to enter the data in the scatter plot we need to use the data button and then data source option so that the data could be entered in the scatter plothence, option c is correct
Answer:
1110 N
Explanation:
First, find the acceleration.
Given:
Δx = 300 m
v₀ = 85.5 km/h = 23.75 m/s
v = 0 m/s
Find: a
v² = v₀² + 2aΔx
(0 m/s)² = (23.75 m/s)² + 2a (300 m)
a = -0.94 m/s²
Find the force:
F = ma
F = (1180 kg) (-0.94 m/s²)
F = -1110 N
The magnitude of the force is 1110 N.
Answer:
The biggest advantage of Solar cookers is their eco-friendliness. By exploitation one you’ll decrease your dependence on gas or electricity, cut back your carbon footprint, and save on fuel and therefore the value of fuel on running home appliances. change of state with star cookers clearly needs daylight, that makes it troublesome to use throughout winter months and on rainy days. change of state conjointly takes a considerably longer time compared to traditional strategies. Users should schedule their change of state time and maximize the employment of daylight. As a result, preparation should begin early within the morning in order that the food may be placed in the cooking utensil by noontide.
Explanation:
Hope this helps
The instantenous velocity is just the slope of the graph at a certain instant. Since the graph is a straight line, its instantenous velocity is uniform through out. v = dx / dt = (40 - 10) / (50 - 0) = 0.6 m/s.
