Explanation:
While studying the velocity of a cheetah over time in a spreadsheet program is given by :
y = 2.2 x + 1.2 ...(1)
We know that,
v=v₀+at ...(2)
v₀ is velocity when t = 0, v is velocity after time t, a is acceleration and t is time.
If we consider time t on x-axis and v on y axis, then only we can draw a plot of equation (2). On comparing equation (1) and (2) we get :
a = 2.2 (but it is not correct as we don't know about axes).
Hence, the correct option is (a) "We cant tell without knowing what was plotted on the horizontal and vertical axes"
The answer is a. over use of petroleum
Temperature is measure of hotness and coldness of of a matter but, thermal energy is can refer to several distinct thermodynanics quantities such as the internal energy of system heat or sensible heat wich are defined as types of transfer heat.
Answer:
Zero
Explanation:
weight of potato sack falls from an airplane is 200 N
Now velocity of fall increases, as increases the air resistance.
The air resistance is equal to 200 N , which is equal to the weight of the sack with potatoes
Then the sack's acceleration in m/s is = 200-200=Zero.
The acceleration here is based on the resistance of the air. if the air resistance is less, the velocity of the sack of potatoes would be high
Sack's acceleration in meters per second is zero
