A) proton

This is simply a matter of actually learning the terms. To wit
<span>A) proton - One of two different particles found in the nucleus of an atom. They have about the same mass as a neutron, and have a positive charge.

B) photon - The basic unit of light.

C) neutron - The other particle found in the nucleus of an atom. They have no electrical charge and are about the same mass as a proton.

D) electron - The particle that "orbits" the nucleus of an atom. They're much lighter than either protons or neutrons, and have a negative charge.

What is the value of the equivalent resistance for the three resistors connected in series?

Harman [31]

The value of the equivalent resistance for the three resistors connected in series will be the sum of the three values.

To find the answer, we have to know more about the equivalent resistance.

<h3>What is meant by equivalent resistance?</h3>

equivalent resistance is the total value of the resistance connected in a circuit.
If n resistors are connected in series, then the equivalent resistance will be,

$R_E=R_1+R_2+..........+R_n$

In our question we have three resistors. Thus, the equivalent resistance will be,

$R_E=R_1+R_2+R_3$

Thus, we can conclude that, the value of the equivalent resistance for the three resistors connected in series will be the sum of the three values.

valentinak56 [21]

Answer: the effective design stiffness required to limit the bumper maximum deflection during impact to 4 cm is 3906250 N/m

Explanation:

Given that;

mass of vehicle m = 1000 kg

for a low speed test; V = 2.5 m/s

bumper maximum deflection = 4 cm = 0.04 m

First we determine the energy of the vehicle just prior to impact;

W_v = 1/2mv²

we substitute

W_v = 1/2 × 1000 × (2.5)²

W_v = 3125 J

now, the the effective design stiffness k will be:

at the impact point, energy of the vehicle converts to elastic potential energy of the bumper;

hence;

W_v = 1/2kx²

we substitute

3125 = 1/2 × k (0.04)²

3125 = 0.0008k

k = 3125 / 0.0008

k = 3906250 N/m

Therefore, the effective design stiffness required to limit the bumper maximum deflection during impact to 4 cm is 3906250 N/m

NEWTONS SECOND LAW LAB REPORT

hram777 [196]

Answer:

Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
