Answer:
10 :)
You have to divide the difference of speed and divide it by the time. So 100-20 would be 80, and if you divide that by 8 it would be 10.
Hope this helps.
The density of the body and the height or the depth of the body since the formula of liquid pressure is density x height gravity
Answer:
1) x_total = 2.7 km=2700 m, 2) t_total = 1926 s, 3) v_avg = 1.40 m / s
Explanation:
1) To solve this uniform velocity problem, we must find the displacement of each part and add them.
x_total = x₁ + x₂
x_total = 0.7 + 2.0
x_total = 2.7 km
2) how long does it take for this tour
truck
v = x₁ / t₁
t₁ = x₁ / v
t₁ = 0.7 / 20
t₁ = 0.035 h
Let's reduce the time to the SI system
t₁ = 0.035 h (3600 s / 1h) = 126 s
when he is walking
t₂ = 30 min (60 s / 1min) = 1800 s
the total time is
t_total = t₁ + t₂
t_total = 126 + 1800
t_total = 1926 s
3) the average velocity is defined as the displacement in the inerval between time
v_avg = x_total / t_total
v_avg = 2700/1926
v_avg = 1.40 m / s

Answer:
<h2>250 m/s</h2>
Explanation:
The speed of the car can be found by using the formula
<h2>v = a × t</h2>
where
a is the acceleration
v is the speed
t is the time
From the question we have
v = 10 × 25
We have the final answer as
<h3>250 m/s</h3>
