Answer:
Acceleration is zero.
Explanation:
The slope of a position time graph gives the velocity of the body.
If the slope is constant means the velocity is constant.
Now, acceleration is the measure of the change in velocity of a body over a given time interval.
So, the acceleration of a body is directly proportional to the change in velocity of the body.
If there is no change in velocity, this means that the acceleration of the body is zero.
Here, the slope is a constant implying that the velocity is a constant. So, there is no change in velocity. This implies that the acceleration is zero for the body in the given time interval.
Thus, if a position time graph has a constant slope, one can infer that the acceleration is zero.
Answer is (b) , because a chemical change happened
Answer:
A divergent boundary is when the plates move apart from each other. When the plates part, magma from under either plate rises and forms a volcano. A hotspot is the third place a volcano can form. This particular type is the least common.
Explanation:
Answer:
intensity
Explanation:
Intensity has no affect on whether or not the photoelectric effect occurs. The determining property is frequency and since frequency and wavelength are inversely proportional, wavelength matters as well
Answer: The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles SO2, or 64.0638 grams.
