Answer:
291 K
Explanation:
To convert Celcius to Kelvin all you have to do is add 273 because 0 Celcius is equal to 273 K.
18 + 273 = 291
Low velocity im pretty sure
Answer:
3.185 x 10^-3 cm/s
Explanation:
dV / dt = 4 cubic cm per second
r = 10 cm
The volume of sphere is given by
V = 4/3 x π x r³
Differentiate both sides with respect to t
dV / dt = 4/3 x π x 3r² x dr/dt
Put dV / dt = 4 cubic cm per second, r = 10 cm
4 = 4/3 x 3.14 x 3 x 10 x 10 x dr/dt
dr/dt = 3.185 x 10^-3 cm/s
<u>Answer:</u>
Chipmunk's average acceleration during the 2.07 s time interval = 0.1256
<u>Explanation:</u>
We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
In this case we need to find acceleration value, we have initial velocity = 1.47 m/s, final velocity = 1.73 m/s and time taken = 2.07 seconds.
Substituting
1.73 = 1.47 + a * 2.07
a = 0.1256
Chipmunk's average acceleration during the 2.07 s time interval = 0.1256
