Larger. How big depends on the size of the vector. But think about pythagoras theorem to solve for the vector.
Answer:
<h2>100 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 25 × 4
We have the final answer as
<h3>100 J</h3>
Hope this helps you
Answer:
The force required to hold the contraction in place is 665.91 N ↑
Explanation:
Given;
specific gravity of oil, γ = 0.75
Volumetric flow rate, V 3.2 Ft³/s = 0.0906 m³/s
where;
is the density of oil
is the density of water = 1000 kg/m³
∴density of oil () = γ × density of water()
= 0.75 × 1000 kg/m³
= 750kg/m³
Buoyant Force = ρVg
= 750 × 0.0906 × 9.8
= 665.91 N ↑
This force acts upward or opposite gravitational force.
Therefore, the force required to hold the contraction in place is 665.91 N ↑
The answer is 36 kilometers per hour, or 10 meters per second.
Answer:
jfonox
Explanation:
since impulse is the change in momentum given by
Impulse = Force x time = change in momentum
I = ft = mv-mu= m(v-u)= jfonox
since the object is initially at rest
u=0,
mv is the final momentum of the object
I =Ft = m(v - 0) = jfonox
mv= jfonox
this show that the final momentum of the object at rest is equal to the impulse received
if any of the mass m, final velocity v or the impact force and the duration of impact of the object is known then we can find or quantify the final momentum.
