The speed after 10 s is 20 m/s
<h3>What is the speed after 10 s?</h3>
Given that we have the following;
force = 2800 N
Mass = 1400 kg
time = 10 s
Recall that;
F = ma
F = force
m = mass
a = acceleration
a = F/m
a = 2800 N/1400 kg
a = 2 m/s^2
Now;
v = u + at
v = ??
u = 0 m/s
a= 2 m/s^2
t = 10 s
v = at
v = 2 * 10
v = 20 m/s

Answer:
0.237 (23.7 %)
Explanation:
The thermal efficiency of an engine is given by:
where
W is the useful work output of the engine
is the heat in input
Here we have:
and the work done is the total heat in input minus the heat exhausted:
So, the efficiency is
(23.7 %)
Answer:
Weather is the conditions (temperature, wind etc.) at a given time, like on that day. Climate, which is what his data would show, is the conditions over an extended period of time like the 3 months he collected data
Answer:
multiply that and divided by 45
