The upper leg applies the exact same amount of force on the knee as the tendon applies on the lower leg. f = 215.6 N
This is only logical as the net result of these forces is the canceling out and the leg staying stable in its position.
The magnitude of a force is how much it accelerates the object it acts on and is represented by a scalar. Size can also be viewed as a strength. Riding a bicycle is a simple example of force magnitude. It is a simple machine that converts human-supplied energy into kinetic energy.
The force exerted on the pedal results in the formation of energy. Work is done to convert this energy into kinetic energy and move the bicycle forward. Force magnitude describes the sum of all forces acting on an object. If all forces act in the same direction the force magnitude increases. If forces act on an object in different directions the magnitude of the force will decrease.

A sine wave is offset 1/6 cycle with respect to time 0. What is its phase in degree and radians?.
The phase in degree and radians is 2π/6 radian.
Solution:
1/6 cycle
1/6 cycle = 1/6 × 2π = 2π/9 radian
Phase angles are measured in radians. A radian is an angle whose arc length equals its radius. One rotation is equivalent to 2π radians or 360 degrees. In electronic signals, phase is the position of the wave at a particular point in time in the waveform cycle. It measures exactly where the wave is within its cycle.
Phase is the position of the instant in the cycle of the waveform. Phase is a dimensionless quantity. A complete cycle is called a phase. Phase is also expressed in radians.

the largest magnetic quantum number (m or ml) of an atom in the ground state is found to be 8. what must be the largest angular momentum quantum number (l)?
The angular momentum quantum number / azimuthal quantum number for the magnetic quantum number of 8 is 7/2
The magnetic quantum number of the atom = 8
The azimuth (or orbital angular momentum) quantum number describes the shape of a particular orbital. This is denoted by the symbol 'l' and its value is equal to the total number of angular nodes in the trajectory. Azimuthal quantum number values can indicate either s, p, d, or f subshells with different shapes.
The angular momentum or azimuthal quantum number can be found using the formula,
m = 2l + 1
where m is the magnetic quantum number
l is the azimuthal quantum number
Let us substitute the known values in the above equation, we get

Two carts, a and b, are connected by a rope 39 ft long that passes over a pulley p. Two carts on a horizontal surface are connected by a rope that passes over a pulley. The distance between the pulley p and the point q on the horizontal surface is 12 ft. Cart a is to the left of point q, and cart b is to the right of point q. Both carts are traveling from right to left. The point q is on the floor 12 ft directly beneath p and between the carts. Cart a is being pulled away from q at a speed of 4 ft/s. How fast (in ft/s) is cart b moving toward q at the instant when cart a is 5 ft from q? (round your answer to two decimal places. ).
The velocity of cart B is 1.73 ft/sec moving towards Q at instant when cart A is 5 ft away from Q .
We have given in question that,
length of rope (l) = 39 ft
the distance between pully point P and horizontal point Q = 12 ft
velocity of cart A = 4 ft/sec
let a = position of cart A relative to Q =0
b = position of cart B relative to Q =0
we want to find out value of db/dt when a = 5 ft .
da/dt = velocity of cart A = 4 ft/sec
Now, consider right angle triangle PQB,
(PB)² = 12² + b² ---(1)
(PA)² = 12² + a² (right angle triangle PQA)
39 = (PA)² + P² = √144+b² + √ 144+a²
so, 39 = √144+b² + √144+ a² ---(2)
differenating equation (2) with respect to time t
we get,0 = b/√144+b² × db/dt + a/√144+a² ×da/dt -----(3)
from equation (2) put a = 5 (given)
39 = √144+b² + √144+25 = 13 + √144+b²
144 + b² = (39-13)² = 676 => b² = 532
=> b = +√532 , b= -√532 but b is on negative side of Q= 0 so, b = -√532
Now, putting value of b, a, da/dt in equation (3)
0 = (-√532 /√144+532 )× db/dt + (5√144+25 )× 4
=> 0 = (-√532/26) × db/dt + 20/13
=> db/dt = ( 20/13 )(26/√532) = 40/√532
= 1.73 ft/sec
Hence , the velocity of cart B moving towards Q is 1.73 ft/sec when cart A is 5 ft away from point Q.

What would happen to the gravitational force felt between two objects if the radius between them were doubled?.
The gravitational force is reduced by a factor of 4 and the distance between two objects is doubled when the radius between them is increased by a factor of 2.
The gravitational force attracts mass-containing objects to one another. We frequently reflect on the gravitational pull of the Earth. This force keeps your body rooted to the ground. In light of the fact that the gravitational force is inversely proportional to the mass of the two interacting objects, heavier objects will be drawn by stronger gravitational forces. The gravitational pull between two objects therefore increases as their relative masses do.

ux = u cosαuy = u sinФDue to the horizontal component of the projection velocity, u cosα, and the vertical component, u sinФ, the projectile moves along the horizontal and vertical directions. So that the projectile's distances along the X and Y axes are given by x and y, respectively, let's assume that at any time t, it reaches the point P.Motion in a horizontal direction: If air friction is ignored, the velocity's horizontal component is i. e. , u cosα will not change. Thus Initial horizontal velocity is given by the formula ux = u cosα. acceleration parallel to the ground, ax = 0.Vertical motion is described as follows:The gravitational effect of gravity causes the projectile's vertical velocity to continuously decrease.
Initial vertical velocity is given by ux = u sinФ.
Ay = -g for acceleration along the vertical.
A projectile's motion can be broken down into two parts because it is a two-dimensional motion both vertical and horizontal motion Independent of one another, these two motions occur. The horizontal and vertical components of the projectile's velocity can be separated into two mutually perpendicular parts.Velocity changes as a result of acceleration. A direction's velocity does not change if acceleration in that direction is zero. The horizontal component of velocity in projectile motion therefore stays constant throughout the motion. A uniform motion can be described as being horizontal.Since the vertical components are continuously impacted by gravity, the vertical motion is uniformly accelerated.
