As a satellite is accelerated away from the Earth by a rocket, the satellite's mass ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
increases
remains the same
decreases
The mass of the satellite will remain the same when it is accelerated away from the Earth.
The mass of an object is a scalar quantity. This implies that mass of an object can be completely described with magnitude only.
The mass of every object in the universe is independent of the gravity and will always maintain the same value from place to place.
Thus, we can conclude that, the mass of the satellite will remain the same when it is accelerated away from the Earth.

What is the anomalous expansivity of water
Answer:
The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4o C to 0o C, and it becomes less dense. The density is maximum at 4 degree centigrade and decreases below that temperature as shown in graph.

The Sun has a mass of 1.99 x 10^30kg [^30 is an exponent] and is 1.5 x 10^11m [^11 is an exponent] from the earth. The planet Earth is 5.98 x 10^24kg [^24 is an exponent]. What is the gravitational attraction between the sun and the earth? G=6.67×10^-11 (-11 is an exponent)
Answer:
F = G M m / R^2 = 6.67E-11 * 1.99E30 * 5.98E24 / (1.5E11)^2
F = 6.67 * 1.99 * 5.98 / 2.25 E21 Newtons
F = 3.53E22 N

the acceleration of a train moving from rest and its speed reaches 36m/sec in 9 sec
Answer:
4 m/s^2
Explanation:
The acceleration is defined as: Δv/Δt (the difference of the velocity over a time period in which happens that difference).
Remember that a difference is calculated by subtracting the initial value of a physical quantity from its final value.
In our case:
Δv = Vfinal - Vinitial = 36m/s - 0 m/s = 36m/s
Δt = 9s
a = Δv/Δt = 36m/s / 9s = 4m/s^2
Use what you know about mass and how you use it to calculate force in the following situation. If each washer has a mass of 4. 9 g, then the mass of two washers in kilograms would be. Given that F = ma, and if 4 washers are attached to the string and car instead of 2, then the applied force on the car will be. Recall a = 10 m/s2.
Considering the change of units and the definition of weight, the mass of two washers would be 0.0098 kg and if 4 washers are attached to the string, then the applied force on the car will be 0.196 N.
Mass of two washers
If each washer has a mass of 4.9 g, then the mass of two washers will be calculated simply by multiplying the mass of 1 washer by the amount you have of them, in this case 2:
4.9 g×2= 9.8 g
Being 1 kg = 1000 g, you apply the following rule of three to make the change of units: if 1000 g equals 1 kg, 9.8 g equals how many kilograms?
[tex]mass=\frac{9.8 gramsx1 kg}{1000g}[/tex]
Solving:
mass= 0.0098 kg
Finally, the mass of two washers would be 0.0098 kg.
Applied forceOn the other side, mass is the amount of matter that a body contains and weight is the action exerted by the force of gravity on the body.
The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.
Weight is calculated as the product of the object's mass and the value of the gravitational acceleration:
W= m×g
In this case, you know:
m= 4.9 g×4= 19.6 g= 0.0196 kg → the mass of 4 washers in kilogramsg= 10 m/s²Replacing:
W= 0.0196 kg× 10 m/s²
Solving:
W= 0.196 N
Finally, if 4 washers are attached to the string, then the applied force on the car will be 0.196 N.

Explanation:
Which statement explains the first law of thermodynamics?.
Energy is transformed and transferred in a thermodynamic system. Option B is correct
First law of thermodynamics:
It states the energy neither be created nor destroyed. It change its form from one to another. It is also known as law of conservation of energy.
It is given by the formula,
[tex]\Delta U = Q - W[/tex]
Where,
[tex]\Delta U[/tex] - change in internal energy
[tex]Q[/tex] - heat added
[tex]W[/tex]- work done by the system
Since, heat is a form of energy, hence it is follow the principle of conservation of energy.
Therefore, energy is transformed and transferred in a thermodynamic system. Option B is correct

9: Electrical energy in the stove is transformed into heat. The heat flows to the water in the kettle, increasing the internal energy of the water. As the energy in the water increases, the water molecules move faster until the liquid water becomes water vapor. The water vapor does work on the whistle, causing it to make a sound. Energy is neither created nor destroyed, it has simply changed form in the process.
