The acceleration due to gravity at the surface of a celestial body can be calculated using the formula:

a = G * M / R^2

where G is the gravitational constant, M is the mass of the celestial body, and R is its radius.

Substituting the lunar and Martian fractional factors for mass over radius squared and multiplying the answers by 9.8, we have:

Acceleration due to gravity at the surface of the Moon:

a = G * Mmoon / Rmoon^2 = G * (0.0123ME) / (0.272RE)^2 = 1.62 m/s^2

Multiplying by 9.8, we have:

a = 1.62 * 9.8 = 15.88 m/s^2

Therefore, the acceleration due to gravity at the surface of the Moon is approximately 1.62 m/s^2, or 15.88 m/s^2 when multiplied by 9.8.

Acceleration due to gravity at the surface of Mars:

a = G * MMars / RMars^2 = G * (0.107ME) / (0.530RE)^2 = 3.71 m/s^2

Multiplying by 9.8, we have:

a = 3.71 * 9.8 = 36.41 m/s^2

Therefore, the acceleration due to gravity at the surface of Mars is approximately 3.71 m/s^2, or 36.41 m/s^2 when multiplied by 9.8.

Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.

Answer:

The submarine's maximum safe depth in sea water is 801.678 m.

Explanation:

P=Po+(rho)*g*h

Max Pressure = Initial Pressure + (Water Density)(Gravity)(Max Depth)

Area of Window = Pi*(Diameter/2)^2 = Pi*(.4m/2)^2 = 0.125664 m^2

Max Pressure= (1.0*10^6 N)/(0.125664 m^2)= 7.95775-E6 Pa

Initial Pressure= 1atm= 101.3kPa= 101300Pa

Water Density (rho) = 1000kg/m^3

Gravity= 9.8m/s^2

So rearranging for h= (P-Po)/((rho)*g)

h=((7.95775-E6Pa)-(101300Pa))/((1000kg/m^3)(9.8m/s^2))= 801.678 m

Answer: the answer is d

Explanation:

If the distance between plates is increased without changing the charge on the plates, the correct answer is a) the

electric field

strength decreases.

The electric field between two large, oppositely charged plates is given by the formula:

E = Q / Aε₀

Where E is the electric field strength, Q is the

charge

on the plates, A is the area of the plates, and ε₀ is the

permittivity

of free space.

If the distance between the plates is increased without changing the charge on the plates, the area of the plates will remain the same, but the electric field strength will decrease.

This is because the electric field lines will be spread out over a larger distance, reducing the electric field strength.

The potential difference between the plates is given by the formula:

V = E d

Where V is the potential difference, E is the electric field strength, and d is the distance between the plates.

Since the electric field strength decreases as the distance between the plates increases, the potential difference between the plates will also decrease.

Therefore, the correct answer is (a) the electric field strength decreases.

The system of two blocks connected by a rope passing over a pulley are M1 and M2, where M1 rests on the triangle edge to the left of the pulley, which makes an angle of theta subscript 1 with the base of the triangle. The coefficient of friction between box M1 and the surface is mu subscript 1. M2 rests on the triangle edge to the right of the pulley, which makes an angle of theta subscript 2 with the base of the triangle.

The coefficient of friction between box M2 and the surface is mu subscript 2. The system sits atop a scalene triangle whose long edge forms the base. The pulley is attached to the apex of the triangle.M1 has a mass of 2.25 kg and is on an incline of angle 1=42.5∘ that has a coefficient of kinetic friction 1=0.205.

The frictional force of the wind on water produces surface currents that travel in a pattern analogous to "wind currents".

Wind, temperature, water density, and the moon's gravitational pull may all affect ocean currents.

Wind-driven waves, sometimes referred to as surface waves, are created by friction between the wind and the water's surface. When wind constantly disturbs the surface of an ocean or lake, a wave crest is created.

Friction slows the wind, which also changes its direction. This phenomenon might lead to surface roughness variations along regional boundaries or turbulence in winds near the surface. Turbulence stirs the lower atmosphere.

The force that is exerted on a rocket is 100,000N

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object exerts a force back on the first object that is equal in magnitude and opposite in direction.

In other words, forces always occur in pairs, and the strength of the force on one object is always equal to the strength of the force on the other object. For example, if you push on a wall, the wall will push back on you with an equal and opposite force. Similarly, if a rocket expels gas out of its engine, the gas exerts an equal and opposite force back on the rocket, propelling it forward.

2. The work done on the motorcycle is equal to its change in kinetic energy, is 550 J.

3. The work done on the runner is equal to his change in kinetic energy, is  100 J.

4. The work done is equal to the negative of his change in kinetic energy, is 100 J.

5. The kinetic energy of the baseball is 67.5 J.

The definition of work done includes both the forces applied to the body and the total displacement of the body. A constant force F is present before to this block. The goal of this force is to move the body d meters in a straight line in the force's direction.

The work done on the car is equal to its change in kinetic energy, so W = ΔKE = 1500 J.

The work done on the motorcycle is equal to its change in kinetic energy, so W = ΔKE = 550 J. Since the motorcycle was initially at rest, its final kinetic energy is equal to the work done on it, so KEf = W = 550 J.

The work done on the runner is equal to his change in kinetic energy, so W = ΔKE = 350 J - 250 J = 100 J.

Since the runner's kinetic energy has decreased, negative work must have been done on him. The work done is equal to the negative of his change in kinetic energy, so W = -ΔKE = -150 J + 250 J = 100 J.

The kinetic energy of the baseball is given by KE = 1/2 mv^2, where m is its mass and v is its velocity. Plugging in the given values, we get KE = 1/2 (0.150 kg) (30.0 m/s)^2 = 67.5 J.

138.6 megacalculations

Explanation:

This is a pretty straightforward one.

All it needs is to convert the degree of measurement.

Dimensions in physics are attributed names, which state the power to which they're are raised. Just as how

Kilo and Mega means the numbers are raised to the power of 3 and 6 respectively. There also exists the ones that indicates how small, such as milli and micro, which are to the powers of -3 & -6.

The question says the IBM computer calculates at an astonishing 136.8 teracalculations.

Tera in physics means it's raised to the power of 12. Thus, the IBM calculates at an astonishing rate of

136.8*10^12 calculations per second.

We're then asked how many calculations it does in 1 micro second. Like I had highlighted earlier, 1 micro second is 1 raised to the power of -6. Or succinctly put,

1 micro second = 1*10^-6.

If the IBM does

138.6*10^12 = 1 second,

Then it does

x = 1*10^-6 second.

When we cross multiply, we have

138.6*10^12 * 1*10^-6, and that is

138.6*10^6 calculations, or say, 138.6 megacalculations.

The IBM does 138.6 megacalculations in 1 micro second, which is still astonishing, by the way
