Answer:
it can change an objects motion
Explanation:
an unblanaced force can make an object start moving
Answer:
Explanation:
Step one:
Given data
work-done in dragging the trash= 236J
applied force= 18.9N
distance moved= 24.4m
Required
The angle of the applied force
Step two:
We know that work done is
WD= F * distance
<em>The work is the product of the horizontal component of the force and the distance.
</em>
Horizontal force = 236 ÷ 24.4
= 9.67 N
Cos θ = Horizontal force ÷ Actual force
Cos θ = (236 ÷ 24.4) ÷ 18.9 = 236 ÷ 461.16
The angle is approximately 59˚
Answer:
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
Explanation:
I believe the correct answer from the choices listed above is option 2. The isotope of an atom that contains <span>40 protons and 51 neutrons and suddenly has two neutrons added to it would be </span>Zirconium-93. We look at a periodic table <span>and find the element with the atomic number 40 which equal the number of protons.</span>
Answer:
F = 0.414 N
Explanation:
Given that,
Magnetic flux density,
The length of the wire, l = 24 m
Current, I = 0.48 A
We need to find the force acting on the wire. The formula for the force is given by:
Put all the values,
So, the force acting on the copper wire is equal to 0.414 N.
