If the pressure on an object, submerged in an unknown fluid is 637,000Pa at a depth of 57.52 m, what is the object's density?

The magnitude of the total electric field due to both charges at this location is 36 v/m. Thus option D is the answer.

This is because the electric field due to each positive charge is 18 v/m, and since the charges are of the same magnitude and opposite in sign, the fields due to each charge will cancel each other out.

The electric field due to a point charge is given by the formula [tex]E = k*Q/r^2,[/tex]where k is the Coulomb constant, Q is the charge, and r is the distance from the point charge. Since the charges are equal and opposite, the net electric field at the point in question is zero.

So, the total electric field due to both charges is the vector sum of the fields due to each charge. Since the charges are equal and opposite, and the point is located in the same distance from both charges, the fields due to each charge will be in the same direction and thus they add up and the total electric field is twice 18 v/m which is 36 v/m.

The net velocity is therefore u= v₀cosθ at the highest or maximum height. Therefore, since the vertical velocity is zero at the highest point, we may conclude that the kinetic energy is at its lowest point.

Lowest kinetic energy is equal to 1 /2 m (v₀cosθ). 2. The point of projection and the point it hits the ground are where the velocity is at its highest magnitude (symmetric motion). Since kinetic energy is related to the square of the velocity, it should therefore be at its highest at the point of projection and the point of impact with the ground.

At the greatest point, potential energy will be highest while kinetic energy will be nil. A system's overall energy balance can be calculated as follows:

Potential energy (PE) continues to decrease and kinetic energy (KE) continues to rise as it descends from its highest point.

The magnitude of the average force on the bumper that collapses 0.2m while bringing a 900 kg car to rest from its initial speed of 1.12m/ s is 2.8×10³N.

The car is hitting an immovable object such as a tree and it's going at 4km/ h and its initial direction is to the left. It comes to a stop within 0.2 m. So the car travels 0.2m and there is only one force acting on it which is the force due to the bumper. So the force applied by the bumper is the net force and the work done by it is the net work done. The net work done is the change in kinetic energy.  The change in kinetic energy is 1/2×m×v². The work done by the bumper is, W=F×d, where d =0.2m.

Now 1/2×900×(1.12)²= F×0.2 , F=(900×1.12×1.12)/(0.2×2) , F=2.8×10³ N.

The best reason deploying the aerial device without first setting apparatus stabilizers is undesirable is the inherent flexibility of the suspension and tires provides poor stability. Thus Option A is the answer.

Deploying an aerial device without first setting the apparatus stabilizers is undesirable as it can lead to poor stability of the device. The inherent flexibility of the suspension and tires of the device can make it difficult to control the device and increase the risk of accidents or damage.

Without stabilizers, the device may not be able to withstand the weight and movement of the aerial device, which could lead to further instability or damage. Furthermore, deploying an aerial device without stabilizers will require more power to lift the device, which can strain the device's power source.

Additionally, deploying an aerial device without stabilizers can put more strain on the surrounding terrain, which can increase the chances of it becoming unstable. Overall, setting the stabilizers before deploying the aerial device is crucial to ensure the safety and stability of the device during operation.

The mass of the liquid in the vat of 1 m diameter and 2 m deep is 2435.54 kg.

Suppose we consider p to be the density of the liquid;

Then the pressure situated at the bottom with a depth (h) of the vat can now be:    P = P0 + pgh

where;  po  = atmospheric pressure.

P-P0 = pgh

p = (P-P0)/gh

We know that: density(p) = Mass/ Volume

The mass of the liquid in the vat can be determined by the formula:

m=pV where; p = (P-P0)/gh

Then;  m = (p = (P-P0)/gh) * Area(A) * h

m =(p = (P-P0)/g) *A

m = (p = (P-P0)/g)* Pie(d/1)^2

replacing the values, we have:

m =(1.3 atm - 1.0 atm)/9.8*Pie(1.0/2)^2

m= (1.3 atm - 1.0 atm)/9.8*(1.013 * 10^5)/1*Pie(1.0/2)^2

m= (3101.020408 *0.7853981

Kinetic energy is the energy that an object possesses as a result of its motion. It is typically represented by the symbol KE and has units of joules (J).

KE = 1/2 * m * v^2

There are several ways that an object can lose kinetic energy. One way is through friction, which occurs when two surfaces are in contact and rub against each other. Friction converts some of the kinetic energy of an object into heat energy. Another way that an object can lose kinetic energy is through air resistance, which occurs when an object is moving through a fluid or gas. Air resistance also converts some of the kinetic energy of an object into heat energy. Another way an object can lose kinetic energy is through collisions. When two objects collide, some of the kinetic energy of the objects is transferred to the other object. If the collision is inelastic, the total kinetic energy of the objects is not conserved, and some of it is converted into other forms of energy, such as heat or sound. Finally, an object can lose kinetic energy due to external forces, such as gravity. When an object is thrown upward, it initially has kinetic energy, but as it rises, it loses kinetic energy as it slows down and eventually comes to a stop at its maximum height. In summary, when an object loses kinetic energy, it means that it is slowing down or stopping.
