Answer:

Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by Newton's second law of motion.

Explanation:

use this, but put it into you own words.

Answer:

The vector sum of forces acting on a particle or body is referred to as net force. The net force is a single force that replaces the effect of the original forces on the motion of the particle. It provides the particle with the same acceleration as all of the actual forces combined, as described by Newton's second law of motion.

Label the layers of the Earth in order from youngest to oldest according to the law of superposition.
zaharov [31]

Answer:

With the increase in depth, age of layer increases.

Explanation:

According to the law of superposition, the layer of the Earth that is present in the deep is considered as the oldest layer while on the other hand, those layer which is present on the top of all layers is considered as youngest layer of earth. When we move from the top layer towards the bottom layer, the age of layer increases or in other words, when we move upward the age of the layer decreases so label the layers of earth on the basis of this phenomenon.

A projectile is fired straight up from ground level. After t seconds it's height is above the ground is h feet where h=-16t^2+14
Rainbow [258]
<span>Plug in 288 for h, move it over to the right side and do the quadratic formula to solve for t. You will get 2 times, in between and including those times will give you the period it is at least 288 ft off the ground.

</span>You can simplify this and not need to use the quadratic. <span>288=−16<span>t^2</span>+144t
</span><span>Divide through by 16 getting
 18=-t^2 + 9t
</span><span><span>t^2</span>−9t+18=0</span><span> Is what you would get after rearranging the equation Now you have something you can easily factor</span><span>

A person is sitting with one leg outstretched and stationary, so that it makes an angle of θ = 27.5° with the horizontal, as the
dangina [55]

here we will use the torque balance about the knee joint

here we can say that

\tau_g = \tau_m

here torque due to weight is given as

\tau_g = 40.1 cos\theta*(l_1 + l_2)

\tau_g = 40.1 cos27.5*(0.105 + 0.150)

\tau_g = 9.07 Nm

now torque due to applied force of muscle

\tau_m = M*sin\alpha * l_1

\tau_m = M*sin30* 0.105

now by torque balance we will have

9.07 = M*0.5*0.105

M = 173 N

so here the magnitude of m will be 173 N

The tuning fork has a frequency of 426.7 is found to cause resonance in a closed column of air measuring 0.186 (the diameter of
lidiya [134]

Answer:

The velocity of the tuning fork sound is 317.4648 m/s

Explanation:

The given parameters are;

The frequency of the fork, f = 426.7 Hz

The length of the closed air column, L = 0.186 m

The diameter of the tube, d = 0.15 m

At the fundamental frequency in a closed tube, we have;

λ = 4·L

Where;

λ = The wavelength of the wave

L = The length of the tube

From the equation for the velocity of a wave, we have;

v = f·λ

Where;

v = The velocity of the (sound) wave

f = The frequency of the wave = 426.7 Hz

λ = 4·L = 4 × 0.186 m = 0.744 m

∴ v = 426.7 Hz × 0.744 m = 317.4648 m/s

Therefore, the velocity of the sound produced by the tuning fork, v = 317.4648 m/s
