Explanation:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased
The three factors are net force, the mass of the object and the direction of the force.
What is acceleration?Acceleration is defined as the rate of change of velocity. It is also defined as the ratio of the net force acting on the body to the mass of the body.
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. and the direction of the force.
As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
Therefore three factors are net force, the mass of the object and the direction of the force.

if a car exerts a area of 3m and a force of 9N what is the pressure exerted by car
Answer:
P = 3 Pa
Explanation:
Given that,
Force exerted by the car, F = 9 N
The area of the car, A = 3 m²
We need to find the pressure exerted by the car. We know that pressure is equal to the force per unit area such that,
[tex]P=\dfrac{F}{A}\\\\P=\dfrac{9\ N}{3\ m^2}\\\\P=3\ Pa[/tex]
So, the pressure exerted by the car is equal to 3 Pa.

For a system mass of 600g and a hanging weight of 0.50 N, determine the acceleration of the system
Answer:
A=0.80
Explanation:
a=2×100/time^2. a=2×100/15.86^2. = a=0.80
The acceleration of the system will be 0.833 meters per second square.
What is newton's second law?The behavior of things is predicted by Newton's first rule of motion when all external forces are equal. The first law, sometimes known as the law of inertia, asserts that if an entity's energies are balanced, its acceleration will be zero meters per second.
When all forces are balanced, an object is said to be in equilibrium and won't accelerate. Newton postulated that an item will only accelerate in the presence of a net or uneven force. An object will accelerate if there is an imbalanced force present, altering its direction, speed, or both.
Let 'm' be the mass of the object in kilogram and 'a' is the acceleration of the object in meters per second square. Then the force on the system is calculated as,
F = ma
For a system mass of 600g and a hanging weight of 0.50 N. Convert the mass of the object into kilogram. Then we have
m = 600 / 1000
m = 0.6 kg
Then the acceleration of the system will be calculated as,
0.50 = 0.6 × a
a = 0.833 meters per second square
The acceleration of the system will be 0.833 meters per second square.
More about newton's second law link is given below.

Answer:
v = 1 i ^ m / s, v = 1 m / s
Explanation:
In this problem we show the difference between vectors and scalars.
The average speed is
v = Δx / Δt
The bold are vectors
Δx = 20-10 = 10 i^ m
v = 10/10
v = 1 i ^ m / s
the unit vector indicates that the velocity is on the x-axis
The average speed is
v =Δx / Δt
v = 10/10
v = 1 m / s
in this case we have a scalar

How many joules of heat energy are needed to raise the temperature of 10.0 g (0.0100 kg) of aluminum from 22 K to 55 K, if the specific heat of aluminum is 897 J/kg * K. Explain your answer
Answer:
296.01 J
Explanation:
From the question,
Q = cm(t₂-t₁)....................... Equation 1
Where Q = quantity of heat, c = specific heat capacity of aluminium, m = mass of aluminium, t₁ = Initial temperature, t₂ = Final temperature
Given: c = 897 J/kg.K, m = 0.01 kg, t₁ = 22 K, t₂ = 55 k
Substitute these values into equation 1
Q = 897×0.01×(55-22)
Q = 897×0.01×33
Q = 296.01 J
Hence 296.01 Joules of heat is required.

Ocean breezes are due to which method of heat transfer?
A. conduction
B. convection
C. greenhouse gases
D. radiation
E. geothermal energy
Ocean breezes are primarily due to convection, which is the transfer of heat through the movement of fluids or gases. The correct option is B.
What is convection?Convection is a method of heat transfer that occurs in fluids (liquids and gases) and involves the movement of material carrying thermal energy. In convection, heat is transferred by the movement of hot fluid from one place to another, which then causes the transfer of heat from the hot fluid to the cooler fluid or surface it comes into contact with.
Convection can occur in two ways:
Natural convection: It occurs due to the density differences caused by temperature variations within a fluid. When a fluid is heated, its density decreases, making it lighter and causing it to rise. As it rises, it cools, becomes denser and falls back down, creating a cycle that is known as a convection current.
Forced convection: In this type of convection, a fluid is forced to flow over a surface or through a channel, by an external agent like a fan or pump. The forced flow enhances the rate of heat transfer from the surface or through the channel, as compared to natural convection, where the fluid flow is driven only by buoyancy forces.
Convection is a very important process for heat transfer in many natural and industrial applications, including heating and cooling systems, meteorology, oceanography, and more.
Here in the Question,
Ocean breezes are primarily due to convection, which is the transfer of heat through the movement of fluids or gases. As the sun heats up the surface of the ocean, the air above it also heats up and rises. This creates a low pressure area that draws in cooler air from over the land, resulting in a breeze that blows from the ocean towards the shore. This is why sea breezes are generally felt during the day, when the land is warmer than the sea, and why they tend to die down at night, when the opposite occurs.
Therefore, The correct answer is B i.e convection.

What is the equivalent resistance of a circuit that contains four 75.0 resistors connected in parallel with a 100.0 V battery?
Answer:
18.75 ohms.
Explanation:
From the question,
]When four resistors are connected in parallel in a circuit,
The equilvalent resistor is given as
1/R' = 1/R₁+1/R₂+1/R₃+1/R₄............................Equation 1
Where R' = Equivalent resistor.
Given: R₁ = R₂ = R₃ = R₄ = 75.0 ohms.
Substitute these values into equation 1
1/R' = (1/75)+(1/75)+(1/75)+(1/75)
1/R' = 4/75
R' = 75/4
R' = 18.75 ohms.
Hence the equivalent resistance = 18.75 ohms.
Answer:
18.8 ohms

Answer:
A differentiated body is a body that has been heated to the point where it is are further from the sun larger have no solid surface and have many more moons Smaller chunks of material vaporize completely as they pass through its atmosphere
Explanation:
Hope it helps..A body is said to be differentiated when it has been heated to the extent where it is bigger, farther from the sun, has no hard surface, and has a lot more moons. Smaller pieces of the materials entirely evaporate as they pass through their environment.
What is Planet?An enormous, spherical celestial object known as a planet is neither a star nor a remain. The nebular theory, which states that an interstellar cloud collapses out of a nebula to form a young protostar that orbits the sun by a protoplanetary disk, is now the best argument for planet formation. By slowly accumulating material under the influence of gravity, or accretion, planets form in this disk.
The terrestrial planets Mercury, Venus, Earth, and Mars, as well as the planetary nebulae Jupiter, Saturn, Uranus, and Neptune, total at least eight planets in the Solar System. These planets all rotate around axes that seem to be inclined relative to their corresponding polar axes.

0.00 C, before any melting takes place?
A. 140,000 J
B. 290,000 J
C. 56,000 J
D. None of the above
Answer:
Q = 144612 Joules.
Explanation:
Given the following data;
Mass = 2.6 kg
Initial temperature = -27°C to Kelvin = 273 + (-27) = 246K
Final temperature = 0°C to Kelvin = 273K
Specific heat capacity = 2060 J/kgK.
To find the quantity of heat absorbed;
Heat capacity is given by the formula;
[tex] Q = mcdt[/tex]
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 273 - 246
dt = 27 K
Substituting the values into the equation, we have;
[tex] Q = 2.6*2060*27[/tex]
Q = 144612 Joules.
