Suppose the force of friction on a sliding object is 25 N The force needed to maintain a constant velocity is?
100 N
===========================
Answer #2:
That depends on the direction of the pulling force.
The horizontal component of the pulling force must be 100 N.
So the more steeply the rope angles upward, the harder you'd
have to pull on it in order to create a 100N horizontal component.

How Can you tell from a velocity-time graph that the velocity is constant?
velocity is nothing but speed of a body in the given direction. suppose if body is moving with constant velocity then VT graph will be parallel to the X -axis, if not then the VT graph is not parallel to the X-axis it means then object is moving with different velocity or it has its dierection or both velocity and aswell as direction.
What is happening at the plate margin of vesuvius?
I suppose that it is a part of friction between two continental plates.
Does increasing the mass or velocity have the most affect on an object's kinetic energy?
Increasing an object's velocity has a greater effect on its kinetic energy than increasing its mass. This is because kinetic energy is directly proportional to the square of the object's velocity, while it is linearly proportional to the object's mass.
Is it possible for an object to have acceleration and no velocity?
It's possible for an object to have velocity equals to zero at some moment and to have some acceleration (when you throw a baseball upwards with the gravitation present, the ball reaches its maximum point and then starts to come back at its maximum height its velocity is zero while acceleration equals g).
Are herbivores and carnivores warm blooded or cold blooded?
I suppose you can say that most herbivores are warm blooded but there are exceptions (a tortoise would be one), but carnivore are sort of a mixture (sharks are cold-blooded but lions are warm blooded). In conclusion, you can't really pin this one down but I hope this answer helped slightly.
Suppose the force of friction on a sliding object is 10N. what is the force needed to maintain a constant velocity is?
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.
What Suppose a bicycle was coasting on a level surface and there was no friction. What would happen to the bicycle's speed?
If there is no friction, the bicycle's speed will remain constant due to inertia. Once set in motion, it will continue at the same speed unless acted upon by an external force.
How Can you tell from a velocity-time graph that the velocity is constant?

When a longboard has frition is it bad?
Yes, its suppose to be ft and smooth, not any friction.
If the displacement of a body is proportional to square of time will the body be moving with uniform velocity or uniform acceleration?
Let us suppose that the displacement is given by, x = kt2 , where k is constant of proportionality. Therefore, velocity of the body, v = dx/dt = d(kt2)/dt = 2kt Since, velocity depends on time ,the body is not moving with uniform velocity.... Again, acceleration of the body, a = dv/dt = d(2kt)/dt = 2k As the acceleration is independent of time , the body is moving with uniform acceleration..
Suppose velocity is measured kmhr and time is measured in hourswhat is that unit of acceleration?
If velocity is km/hr and time is in hours then acceleration will be in km/hr2

If you push a crate at constant velocity how does friction acting on the crate compare with your pushing force?
If a wagon is moving at a constant velocity, the total applied force must equal the frictional forces that resist the continued motion of the wagon. If they were not equal, the wagon would accelerate. In positive acceleration, it would speed up, and in negative acceleration, it would slow down. Think it through and you'll see that this is the only answer that makes sense. And not only does it make sense, it is true. The laws of physics are in force here.
Suppose you push a cart toward the west In what direction does the force of friction push on the cart's wheels?
east
Why do you wear wedding jewellery at weddings?
To maintain a unified look, I suppose.
What is the independent value is in physics science?
I suppose you mean physical constants such as the Heisenberg constant, the Boltzmann constant, the gas constant, the electron charge and so on. As you can see such values are independent on what kind of experiment you have, where, when and how.
How was velocity of a wave derived?
The velocity=distance/time ,, Suppose that the distance covered is one complete vibration therefore the distance is called wavelength and the time is called periodic time then velocity=wavelength/periodic time also frequency= 1/periodic time therefore the velocity=wavelength*frequency
