Answer:
The answer is C. More water is entering the oceans from melting sea ice than is leaving through evaporation.
Explanation:
- <u><em>A primary cause for increased mass of water entering the ocean is the calving or melting of land ice (ice sheets and glaciers)</em></u>
Answer:
350 N
Explanation:
From the question given above, the following data were obtained:
Mass (m) of Go Kart = 35 kg
Initial velocity (u) = 12 m/s
Distance (s) = 7.2 m
Force (F) =?
Next, we shall determine the acceleration of the Go Kart. This can be obtained as follow:
Initial velocity (u) = 12 m/s
Distance (s) = 7.2 m
Final velocity (v) = 0 m/s
Acceleration (a) =.?
v² = u² + 2as
0² = 12² + (2 × a × 7.2)
0 = 144 + 14.4a
Collect like terms
0 – 144 = 14.4a
– 144 = 14.4a
Divide both side by 14.4
a = – 144 / 14.4
a = – 10 m/s²
The negative sign indicate that the Go Kart is decelerating when the brake was applied.
Finally, we shall determine the force the Go Kart have when the student locked the brake. This can be obtained as follow:
Mass (m) of Go Kart = 35 kg
Acceleration (a) = 10 m/s
Force (F) =?
F = ma
F = 35 × 10
F = 350 N
Thus, the Go Kart has a force of 350 N when the student locked the brake.

In this item, there needs to be a basis as to how many significant numbers can be present in a certain figure. If the answer 327.66 m/s is to be expressed as a 3 significant figures only, the answer would have to be 328. What was done here is to simply round up the units digit of the number since the decimal place (tenths) digit has a value of greater than 4.
The answer to this item is therefore letter B.
