2(5) + 2 (z) = 10{3}
10 + 2z= 30
2z=20
z=10
Answer:
use a hammer to hit it
Explanation:
if u hit it u will be able to hear the shattered noise
Answer:
Explanation:
Acceleration is given by
where
is the change in velocity
is the time interval in which the change in velocity occurs
To find the acceleration at 1 second, we can take the data at t = 1 s and t = 2. We find:
So, the acceleration is
Using the kinematics equation vf = vi + at we plug in all known values 15 = 5 + a*1 solving for a we get 10m/s^2
Answer:
dT(t)/dt = k[T5 - T(t)]
Explanation:
Since T(t) represents the temperature of the object and T5 represents the temperature of the surroundings, according to Newton's law of cooling, the rate at which an object's temperature changes is directly proportional to the difference in temperature between the object and the surrounding medium, that is dT(t)/dt ∝ T5 - T(t)
Introducing the constant of proportionality
dT(t)/dt = k[T5 - T(t)]
which is the desired differential equation
