What force is required to give an object with mass 2000 kg an acceleration of 3.5 m/s2
2 answers:
<u>Answer:</u> The force exerted on the object is 7000 N
<u>Explanation:</u>
Force is defined as the push or pull on an object with some mass that causes change in its velocity.
It is also defined as the mass multiplied by the acceleration of the object.
Mathematically,
where,
F = force exerted on the object
m = mass of the object = 2000 kg
a = acceleration of the object =
Putting values in above equation, we get:
Hence, the force exerted on the object is 7000 N

Answer:
Explanation:
During an energy transfer, the collision loss for an electron can be determined by using the formula:
However; from the total stopping power & power loss of the electron;
where;
Z = atomic no. for lead = 82
E = 1.9 MeV
∴
radiational energy loss = collisional energy loss
= 0.19475

Normally, the traditional lead shielding in its pure shape contains high brittleness. However, the functionality of this carbon group chemical element is useful for protection because it has an excessive density.
Initially, the conventional lead protection however reduces the mild clarity at the same moment as plexiglass is useful for light transmittance and readability.
Moreover, the traditional lead with its high density and thickness reduces observation features, in the meantime, the plexiglass is a whole lot higher than the stated.
Finally, plexiglass contains a high dimensional balance with an excessive dielectric constant.
Let
dV = dt = water is flowing in at a rate of 12 ft3 / min.
h = the depth of the water.
dh / dt = the rate of change of the depth.
First you must find the volume of the cone as a function of "h". Then you must derive the volume of the cone with respect to time. Finally clear dh / dt.
