The parameters are as follows: length of steel, L = 4.20m; mass of steel, m = 580 kg; and mass of work, m = 75.0 kg.

The following formula is used to determine how much torque the worker's weight and the weight of the beam will exert on the bolt;

the beam's center of gravity [tex]\frac{4.20}{2} = 2.1 m[/tex]

[tex]T_{t}=T_{1}+T_{1}[/tex]

The magnitude of the force exerted by you on your friend is equal to the magnitude of the force exerted by your friend on you.

The information given to us is the you have a tug-of-war with a friend who is the same size and weight as you are. we both pull as hard as we can, but neither of you seems to be winning. You move a little one way or the other, but mostly you are just at rest (although sweating some). The magnitude of the force exerted by you on your friend is equal to the magnitude of the force exerted by your friend on you. This is because of newton's third law of motion that, forces are always equal and opposite, so when you pull on your friend, they pull back on you with an equal and opposite force. Therefore, both forces are the same.

A typical flashlight battery will produce a 0.50-A current for about 3 h before losing its charge.The number of electron is: 3.4 × 1O²²

Traditional flashlights emit light from an incandescent bulb that is powered by a battery. Battery current warms the filament wire within the light bulb, causing it to glow and emit light.

When a flashlight's circuit, which consists of the batteries, switch, and light bulb, is complete, the chemical energy in the batteries is transformed into electrical energy. The light bulb converts electrical energy into light (electromagnetic / radiant energy) and some heat (thermal energy).

Given that,

current = 0.50 A

time = 3 h

The expression for current, I = Q/t

where Q = charge and t = time taken

The mathematical expression for quantization of the charge,

Q = N × e

Where, N = is the number of the charged particle and e = is the charge on an electron.

Now, calculate the amount of charge,

I = Q/t

or, 0.50 A = Q / [(3h ×3600 sec)/1 h]

or, Q = 5400 C

Next, calculate the number of electrons:

Q = N × e

or, 5400 C = N × ( 1.6 × 10⁻¹⁹ C)

or, N = 3375 × 1O¹⁹

Thus, the number of electron is: 3.4 × 1O²²

Following the putty's adhesion to a ball, both are propelled forward by the combined momentum of two units.

Momentum was defined as the amount the the body's motion. As momentum depends on both velocity and the direction of a body's motion, it is quantified by "mass velocity". Since velocity is indeed a vector and mass is a scalar, momentum is a vector. Mass times speed equals momentum.

Quantity may be assessed in the this scenario since a moving item has mass and momentum. If such an object is stationary, it has no momentum.

The system's momentum is conserved in this instance of an inelastic collision.

Here, the principle of momentum conservation will be applied.

As either a result, following a collision, the combined momentum will equal the initial momentum. The answer "2 units" is the one that is right.

Chondrocytes are housed in lacunae, which are hollow areas in cartilage.

A supporting connective tissue without a blood supply is cartilage.

Cartilage is isolated from other tissues by a layer called the perichondrium.

Cells called chondrocytes, or chondrocytes in lacunae, are present in the connective tissue of cartilage. How "bendy" cartilage is depends on how many chondrocytes are present in it.

Now, we shall convert 90 mmHg to SI unit of pressure (i.e Pascal) as illustrated below:

From conversion identities,

760 mmHg = 101325 Pa

Therefore,

90 mmHg = (90 mmHg × 101325 Pa) / 760 mmHg

90 mmHg = 11999 Pa

Speed the block has as it passes through equilibrium if  the horizontal surface is frictionless is 0.79 m/s and if the surface is with friction then the speed is 0.53 m/s.

Friction is the resistance to motion of one object moving relative to another. There are two main types of friction, static and kinetic friction.

Given mass of the block m = 2.00 kg and

The force constant k = 500 N/m

The block is pulled to a position of x, = 5.00 cm = 0.05 m

a) Hence the potential energy stored in the block is

U = 1/2Kx^2 =. = 0.625 J

as the surface is frictionless, hence the potential energy changes into kinetic energy

And is given by

1/2mv² = 0.625 J

Given mass of the block is m = 2.00 kg

Hence, 1/2(2.00)v² = 0.625

v=0.79 m/s

b) Now when the surface is with friction,

Then the amount of work done in over coming the friction is

W=umgx=(0.35) (2.00)(9.8) (0.05) = 0.343 J

Hence the loss in energy from the potential energy is

ΔU = U-W= 0.625 J - 0.343 J = 0.282 J

Hence this energy is converted into the kinetic energy of the block

Hence 1/2 mv^2 = 0.282 J

Because of size of the Earth and how far out from its core humans are on its surface, attraction (or the acceleration caused by gravity) equals 9.81 m / sec squared on Earth's surface.
