Assuming a constant density, the size of an object scales as its mass raised to the 1/3 power.

Assuming a constant density, the size of an object scales as its mass raised to the 1/3 power.

The surface area of a sphere scales as the square of its radius, therefore if the egg shell is approximately spherical, its surface area would scale as the square of its radius raised to the power of 2, or A∝r^2. Since the mass of the egg shell is proportional to its volume, which is proportional to the cube of its radius, or V∝r^3, we have:

A∝r^2 and V∝r^3

Combining these two relationships, we have:

A∝r^2 and V∝r^3

A∝(V^(2/3))^2 = V^(4/3)

Substituting in the relationship between the mass of the egg shell and the volume:

V∝M^(1.132)

A∝M^(2.264)

Therefore, the surface area of the egg shell scales with the overall mass of the egg to the power of 2.264.

The force experienced by a point charge in an electric field is given by Coulomb's law where F is the force, k is the Coulomb constant, q1 and q2 are the charges, and r is the separation between the charges.

The direction of the force is given by the direction of the electric field at that point, which is proportional to the gradient of the electric potential at that point. In this case, the arrangement of charges is symmetrical, with equal and opposite charges at each vertex of the square and a positive charge at the center. This means that the electric field at the center of the square will be zero, as the forces from each charge will cancel out.

The work done in ergs is 0.0104 joules and 0.002475 calories.

Work can be calculated using the definition of work as force times distance, or W = F * d, where

W is the work done,

F is the force,

d is the distance moved.

Given a constant force of 104 dynes acting to move an object by 100 cm, we can calculate the work done as follows:

W = F * d = 104 dynes * 100 cm

= 10,400 dyne cm = 10,400 g cm cm.

One erg is defined as the amount of energy required to move a force of one dyne over a distance of one centimeter, so the work done in ergs is equal to the work done in dyne cm, or 10,400 ergs.

One joule is equal to 10^7 ergs,

so the work done in joules is 10,400 ergs / 10^7 ergs/joule = 0.0104 joules.

One calorie is defined as the amount of energy required to raise the temperature of 1 gram of water by 1 degree Celsius, and is approximately equal to 4.184 joules. Therefore, the work done in calories is 0.0104 joules / 4.184 joules/calorie = 0.002475 calories.

The required acceleration to stop the car in 70 meters while going at 50 miles per hour is approximately 7.95 m/s².

The distance it takes to stop a moving car can be calculated using the formula:

d = v² / (2 x a)

where d is the stopping distance, v is the initial velocity (in this case, 50 miles per hour), and a is the acceleration.

Rearranging this formula to solve for acceleration

a = v² / (2 x d)

Substituting the given values:

a = (50 miles/hour)² / (2 x 70 m)

First, the velocity must be converted to meters per second:

v = 50 miles/hour x 1609.34 m / 3600 s

= 22.352 m/s

a = (22.352 m/s)² / (2 x 70 m) = 22.352² / (2 x 70)

The magnitude of the momentum of the two dice system is 0.003 kg m/s.

Momentum is a measure of an object's motion, defined as the product of its mass and velocity. It represents the amount of motion an object has, and the direction of that motion. In physics, momentum is a conserved quantity, meaning that the total momentum of a system remains constant unless acted upon by an external force. This is reffered to as the law of conservation of momentum. The greater an object's mass and velocity, the greater its momentum.

The magnitude of the momentum of an object can be calculated by multiplying its mass by its velocity.

For the blue die:

mass = 6.5 g = 0.0065 kg (converted from grams to kilograms)

velocity = 12 m/s

momentum = 0.0065 kg × 12 m/s = 0.078 kg m/s

For the green die:

mass = 7.5 g = 0.0075 kg (converted from grams to kilograms)

velocity = -10 m/s (opposite direction)

momentum = 0.0075 kg × -10 m/s = -0.075 kg m/s

The total momentum of the two dice system can be found by adding the momenta of each individual die:

total momentum = 0.078 kg m/s + (-0.075 kg m/s) = 0.003 kg m/s

So, the magnitude of the momentum of the two dice system is 0.003 kg m/s.

When a cannon fires a cannonball, the cannon will recoil backward. It is because the momentum of cannonball and the cannon is conserved.

The conservation of momentum principle states that the amount of momentum within a problem domain remains constant; momentum is neither created nor destroyed, but only changed by the action of forces as described by Newton's laws of motion.

p: the system's initial momentum (total momentum before an event)

p′: the system's final momentum (total momentum after the event)

The total momentum is zero before the cannon is fired. This is due to the fact that neither object is moving. When a cannon is fired, the cannonball accelerates forward and the cannon accelerates backward. As a result, the total momentum of the cannon and cannonball after firing is also zero. Finally, it is obvious that a cannon will recoil backward when a cannon fires a cannonball because the momentum of the cannonball and the cannon is conserved.
