The center of mass is the point located in an average position concerning the objects' positions and their masses. (a/3;a/3) is the location of the COM.  

The center of masses of a given system of particles or objects is the position under which all external forces are acting. Any uniform force acts on this point.

This position is the average position of all the components of the system concerning their masses. It can be placed in one, two or three dimensions according to the system.

Coordinate X of the center of masses is given by the following formula,

Xcom = Σ(Ximi) / Σmi

This is the adition (Σ) of each particle position on the X-axis (Xi) multiplied by their mass (mi), and the result divided by the summation of all masses -total mass-.

In the same way, coordinate Y of the center of masses is given by the following formula,

Ycom = Σ(Yimi) / Σmi

This is the adition (Σ) of each particle position on the Y-axis (Yi) multiplied by their mass (mi), and the result is divided by the summation of all masses.

The center of masses is located in the position (X, Y).

According to this framework, we can get the coordinates of the center of masses for this bidimensional system. Coordinates can be expressed in meters or centimeters (m or cm).

Data:

     Particle ⇒ (X;Y)

Coordinate X  ⇒  Xcom =  Σ(Ximi) / Σmi

                             Xcom =  (0m) + (0m) +(am) / m +m +m

                             Xcom =  am / 3m

                             Xcom =  a/3

Coordinate Y  ⇒  Ycom =  Σ(Yimi) / Σmi

                             Ycom =  (am) + (0m) +(0m) / m +m +m

                             Ycom =  am / 3m

                             Ycom =  a/3

Coordinates of the center of masses, (X;Y) = (a/3 ; a/3)

(a/3 ; a/3) is the location of the center of mass in the proposed bidimensional system.

On conservation of momentum:

(a) The cart goes in the opposite direction as the man does.

(b) With a speed of 0.07 m/s, the cart proceeds in the opposite direction as the guy.

(c) the cart starts moving in the forward direction with the same velocity of 0.07 m/s.

(a) As per the conservation of momentum, the total momentum of the system is conserved. Initially, the system was at rest, but when the man starts walking towards the other end, he gains some momentum in the forward direction, which the cart has to compensate for. So, the cart moves in the opposite direction to that of the man's motion.

(b) Assume that the man moves a distance of 10 m, i.e., the length of the cart.

Therefore, the total distance covered by the man is 20 m (10 m forward and 10 m backward).

The momentum gained by the man while walking forward is (70 kg) x (1.0 m/s) = 70 kg m/s.

As the total momentum of the system is conserved, the cart gains an equal and opposite momentum of -70 kg m/s.

The mass of the cart is 1,000 kg, so its velocity can be calculated using the conservation of momentum formula:

Total initial momentum = Total final momentum

0 = (70 kg) x (1.0 m/s) + (1,000 kg) x V

V = -0.07 m/s

So, the cart moves in the opposite direction to that of the man's motion with a speed of 0.07 m/s.

(c) When the guy comes to a complete halt at the back of the automobile, he loses the momentum he got while going forward, and the cart obtains equal and opposite motion. As a result, the cart begins going ahead at the same velocity of 0.07 m/s.

The required diameter of the beam at the fixed end is c. 292 mm.

Why the required diameter of the beam at the fixed end is c. 292 mm?

To find the required diameter of the beam at the fixed end, we can use the formula for maximum bending induced shear stress in a cantilever beam:

τ_max = (3/2) ˣ (V/A)

where τ_max is the maximum bending induced shear stress, V is the maximum shear force at the fixed end, A is the cross-sectional area of the beam at the fixed end.

First, we need to find the maximum shear force at the fixed end of the cantilever beam. This can be done using the formula for the total load on the beam:

W = wL

where W is the total load, w is the uniformly distributed load, and L is the span of the beam. Substituting the given values, we get:

W = 30 kN/m ˣ 2 m = 60 kN

Next, we can find the maximum shear force at the fixed end using the formula:

V = W/2

Substituting the value of W, we get:

V = 60 kN/2 = 30 kN

Now we can use the formula for maximum bending induced shear stress to find the required diameter of the beam at the fixed end. Rearranging the formula, we get:

A = (3/2) ˣ (V/τ_max)

Substituting the given values, we get:

A = (3/2)ˣ (30 kN/(2 N/mm²)) = 67,500 mm²

Finally, we can use the formula for the area of a circular cross section to find the required diameter of the beam:

A = (π/4) ˣ D²

Rearranging the formula, we get:

D = sqrt((4ˣA)/π)

Substituting the value of A, we get:

D = sqrt((4ˣ67,500 mm²)/π) = 292 mm

Therefore, the required diameter of the beam at the fixed end is c. 292 mm.

If a car covers a distance of 300 km with a speed of 60 km/h and then covers a distance of 450 km with a speed of 90 km/h then the average speed of the car is 75 km/h.

- The formula to calculate average speed is:  Average speed = Total distance covered / Total time taken

To find out the total distance covered by the car, we need to add the two distances covered by the car.

Therefore, Total distance covered = 300 km + 450 km= 750 km

- The time taken to cover 300 km with a speed of 60 km/h is given by:

Time taken = Distance / Speed

= 300 km / 60 km/h = 5 hours

- Similarly, the time taken to cover 450 km with a speed of 90 km/h is given by:

Time taken = Distance / Speed

= 450 km / 90 km/h = 5 hours

- Total time taken = 5 hours + 5 hours = 10 hours

- Now we can substitute these values in the formula of average speed:

Average speed = Total distance covered / Total time taken

Average speed = 750 km / 10 hours

Average speed = 75 km/h.

The S.I. unit of E is NC^-1 and that of B is NA^-1 m^-1, then unit of E/B is A m/C (ampere meter per coulomb). This unit represents the ratio between the electric field and the magnetic field, indicating the strength and direction of the electromagnetic field.

The SI unit of electric field (E) is NC^(-1) (newton per coulomb) and the SI unit of magnetic field (B) is NA^(-1) m^(-1) (tesla). To determine the unit of E/B, we need to divide the unit of E by the unit of B.

Dividing the unit of E (NC^(-1)) by the unit of B (NA^(-1) m^(-1)), we can simplify the expression:

E/B = (NC^(-1))/(NA^(-1) m^(-1))

To simplify this expression, we can cancel out the common units in the numerator and denominator:

E/B = (N/C)/(N/(A m))

Now, let's simplify further by dividing the numerator and denominator:

E/B = (N/C) * (A m/N)

Canceling out the common units:

E/B = (A m)/(C)

Therefore, the unit of E/B is A m/C (ampere meter per coulomb).

If there are both electric and magnetic fields in the room and their effects on the charged particle cancel, and the electric field points upward, then the direction of the magnetic field is downwards.

The electric force on a charged particle is provided by an electric field, whereas the magnetic force is provided by a magnetic field. The effect of the electric and magnetic fields on the motion of the particle is a function of the relative directions and magnitudes of the two fields.

If the magnetic field is perpendicular to the electric field and the particle's velocity, the magnetic force is at right angles to both the electric force and the velocity, and it does not adjust the particle's speed. If the electric and magnetic forces on a charged particle are equal and opposite, they cancel each other out, resulting in no acceleration of the charged particle. Since the electric field is pointing upward, the magnetic field should be pointing downward.

In conclusion, the direction of the magnetic field is downward if the electric field is pointing upward, according to the given condition.

Check if the draft pressure switch is closed when troubleshooting an induced draft gas furnace if the induced draft fan comes on but the igniter is never energized.

When troubleshooting an induced draft gas furnace, if the induced draft fan comes on but the igniter is never energized, one should check the draft pressure switch. The draft pressure switch is used to verify that the correct amount of airflow is present to ensure safe combustion. If the switch is closed, the fan will be energized, allowing it to bring in the required air and carry it over the heat exchanger. When the switch is open, the fan will not operate, which means that it will not ignite the gas.

If the draft pressure switch is not closed, it may be due to a clogged venting system or improper flue installation. When the venting system is clogged, it will prevent the switch from closing, causing the igniter not to energize. To solve this problem, one should check the venting system to ensure it is free of debris.
