Answer:
-5.6m/s²
Explanation:
Given parameters:
Initial speed = 11.2m/s
Time of running = 2s
Unknown:
Acceleration of the puppy = ?
Solution:
Acceleration is the rate of change of velocity with time.
So;
Acceleration =
final speed = 0m/s
Acceleration = = -5.6m/s²
The puppy's acceleration is -5.6 m/s².
Acceleration is a measure of how quickly an object changes its speed. The formula for acceleration is a = Δv / Δt, where Δv is the change in velocity and Δt is the change in time. To find the puppy's acceleration, we can use the formula for acceleration:
acceleration = (final velocity - initial velocity) / time.
In this case, the initial velocity is 11.2 m/s and the final velocity is 0 m/s (since the puppy stops running). The time taken to stop is 2 s.
Substituting the values into the formula, we get:
acceleration = (0 m/s - 11.2 m/s) / 2 s.
Simplifying the equation gives us the acceleration of the puppy, which is -5.6 m/s².

C. yellow
D. white
Answer:
C. yellow
Explanation:
The stars have different color depending on their temperature, in general the more blue or violet a star is, the higher its surface temperature, and the more orange or red, the lower its surface temperature.
In the stellar classification, stars with temperatures ranging from 5000K to 6000K are G type stars which are characterized by having a yellow color.
An example of a G-type star is the sun, which has a surface temperature of around 5700K.
When a lower tank is damaged, the incoming sea water pushes the oil in the damaged tank up into the ballast tank. Because of the hydrostatic pressure, there is an automatic transfer out of the damaged tank. The double-hull design is aimed at the probability of zero outflow.
