Answer:

The four fundamental forces magnitude and range are in order of Strong Nuclear Force > electromagnetic force > weak nuclear force > gravitational force.

Explanation:

The 4 fundamental force are weak nuclear force, strong nuclear force, em force and the gravitational force are discussed below.

Strongest force is the strong nuclear force as compared to all of them. It is very useful for capturing the atoms nucleus together despite the large repulsion which is occur between the same charges due to protons in the nucleus.

Electromagnetic Force is the 2nd strongest fundamental force. Magnetism and electricity was thought to be of 2 separate forces.

Weak Nuclear Force involves the W and Z bosons exchange. It has a very short range of

Gravitational Force is the weakest between all the fundamental forces. However, due to its long range it is the most dominant force. It follows the inverse square law like but it is always attractive in nature.

5. Calculate the final speed of a 110-kg rugby player who is initially running at 8.00 m/s but collides head-on with a padded go

bulgar [2K]

Answer:

0.8 m/s

Explanation:

From Newton's third law of motion,

Impulse on a body = Change in momentum of the body

Ft = m(v-u) ......................... Equation 1

Where F = force on the body , t = time, m = mass of the body, v = final velocity, u = initial velocity,

Note: Taking the direction of the initial velocity as negative,

Given: F = 1.76×10⁴ N, t = 5.5×10⁻² s, m = 110 kg, u = -8.0 m/s

Substitute into equation 1

1.76×10⁴ ( 5.5×10⁻²) = 110[v-(-8.0)]

968 = 110v+880

110v = 968-880

110v = 88

v = 88/110

V = 0.8 m/s

Hence the final velocity = 0.8 m/s

what aspect of receiver analog-to-digital conversion determines the maximum receive bandwidth of a direct digital conversion sdr

Zepler [3.9K]

Answer:

The sample rate determines the maximum receive bandwidth of a direct digital conversion SDR. An analog signal must be sampled at twice the rate of the highest frequency component of the signal by an analog-to-digital converter so that the signal can be accurately reproduced.

A student takes the elevator up to the fourth floor to see her favorite physics instructor. She stands on the floor of the eleva

never [62]

Answer:

N = 1364 N

Explanation:

given data

accelerate upward = 5.70 m/s²

mass = 88.0 kg

solution

normal force is in upward direction so, weight of the student in downward direction and acceleration is in upward direction so formula is express as

N - mg = ma ...........................1

N = m × (g+a)

put here value

N = 88.0 × (9.8 + 5.70)

N = 1364 N

A square conducting plate 52.0 cm on a side and with no net charge is placed in a region, where there is a uniform electric fiel

Mrac [35]

Explanation:

Given: uniform electric field E= 82.0 kN/C.

a) charge density σ =ε_0 E.

therefore, $\sigma =82\times10^3\times3.85\times10^{-12}\\=0.0000003157= 315.7 nC/m^2$

b)Total charge on each face = σA

q=σA

$=315.7\times10^{-9}\times52\times10^{-4}\\=1.614\times10^{-9}= 1.614 \text{ nC}\\\text{Similarly on the other face } = -1.614 \text{ nC}$

A kettle transfers 6,000j of energy electrically. 1,500j of this is wasted. what is the efficiency of this kettle?

Mashcka [7]

Answer:75 percent

Explanation:so in order tro fin d thge efficiency i used the forumla ,efficency=useful output energy/input energyx100%,in order to use this formula i needed the output,which i found by subtracting the input energy with wasted energy,that gave me the output,and after founding the output,i put that into the formula,

output energy=input energy - wasted energy

output energy=6000j-1500j

output energy=4500

put that into the formula

efficiency =output energy/input enrgy x100%

efficiency=4500/6000 multiplied by 100%

efficiency=0.75x100%

efficiency=75%
