tension-the force when something is pulled tight from two opposite directions
friction-the opposite force an object experiences when it moves across a surface
normal force-the force of an object upon another object
gravity-the force of very large objects such as planets that pull objects towards themselves

A 50 W immersion heater is switched on for 1 minute to heat up a cup of water. How much energy is supplied to the water?
Answers
Answer:
3000 joule
Explanation:
power= work done/ time
50= work done/60 second
so , work done will rise up heat = energy= 50×60 joule
the movement of liquid particles through a circular motion
Answers
Answer:
Solids - vibrational (and rotational); moving very slowly.
Liquids - vibrational, rotational, and translational; moving quickly.
Gases - vibrational, rotational, and translational; moving very quickly.
Explanation:
Particles are always moving. No matter what. There is a certain point where they move so slowly it is considered minuscule, but they are in fact moving.
Thus, in solids, liquids, and gases, you can expect particles to move in a certain trend. That trend is average kinetic energy of the particles and the forces holding them together (attraction).
Explanation:
The movement of liquid particles through a characteristic path or circlar motion

Cara is swimming in a river. She can swim downstream up to a maximum speed of 66 meters per-minute. If she is swimming downstream at half of her maximum speed, how far will she swim in 13 minutes?
Answers
Half of 66 is 33 so that’s half of her maximum speed.
You then take 33 and times it by 13.
66/2=33
33x13=429

During a hockey game, the puck slid from the center line directly to the goal line in 1.5 seconds. The center line is 27 meters from the goal line. As the puck slid, it was chased by a hockey player skating at 9.5 meters per second. What was the puck's velocity?
Answers
Answer: The pucks velocity was 18 meters per second.
Explanation: First I divided 27 by 3 because of the 1.5 seconds and the i multiplied my answer by 2 and got that it traveled 18 meters in 1 second.
During a hockey game, the puck slid from the center line directly to the goal line in 1.5 seconds. The center line is 27 meters from the goal line. As the puck slid, it was chased by a hockey player skating at 9.5 meters per second. And the puck's velocity is 18 m/s.
What is Average velocity?
Average velocity can be defined as the average rate of change of displacement with respect to time. Average velocity is a measure for distance traveled in a given time.
We can calculate the average velocity by the rule
v = s/t (m/s)
where s is the displacement and t is the time
Mathematically,
speed = distance/ time
The puck traveled a distance of 27 m in 1.5 seconds
The speed of the puck is thus;
27/1.5 = 18 m/s
Thus, the puck's velocity can be calculated as 18 m/s.

A ball of mass 100g thrown by a man moves at a velocity of 100m/s. what is the momentum? need the answer step by step plssss!! i need it fast!!!!!!!
Answers
Explanation:
Mass of the ball= 100 g = 0.1 kg
Velocity of the ball before collision=10 m/s
Momentum of the ball before collision, p(i)=mv= 0.1×10=1 kgm/s
Since, ball returns back with same velocity
Therefore, velocity of ball after collision = -10 m/s (-ve sign due to opposite direction)
So, momentum of ball after collision,p(f) = 0.1 ×(-10) = -1 kgm/s
Now, Impulse generated in the ball= change in momentum= p(f)-p(i)= -1–1= -2 kgm/s

What is soil erosion
Answers
Answer:
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage.
Answer:
It is the breakdown of soil due to natural processes
Explanation:
Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide
