Answer:
a. 6
b. 6 m/s²
c. 300 m to the right
d. 30 secs
Explanation:
slope = rise /run
60-0/10-0
= 6
b. slope = acceleration = 6 m/s²
c. d=ut+1/2at²
t=10 (segment A last for 10 secs)
u - initial velocity = 0
so d = 0(10)+1/2*6*10²
=300 m
Answer:
There are seven fundamental physical quantities they are: length, mass, time, electric current, temperature, amount of substance, and light intensity.
A its Stratosphere, Sorry I didn't see your answer, its bilogy I think not physics.. :)
Answer:
Explanation:
Mass of the cable car, m = 5800 kg
It goes 260 m up a hill, along a slope of 
Therefore vertical elevation of the car = 
Now, when you get into the cable car, it's velocity is zero, that is, initial kinetic energy is zero (since K.E. = 
). Similarly as the car reaches the top, it halts and hence final kinetic energy is zero.
Therefore the only possible change in the cable car system is the change in it's gravitational potential energy.
Hence, total change in energy = mgh = 
where, g = acceleration due to gravity
h = height/vertical elevation
Answer: the statement that describes the transformation of energy is statement B (The potential energy was turned into Albertine's kinetic energy, which was then converted into internal(thermal) energy.)
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
Throughout Albertine's journey, no energy was lost. Her potential energy was converted to kinetic energy and then to thermal energy of the body.
