What else can I help you with?
Is constant speed current velocity?
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
What is an example of constant speed with changing velocity?
Velocity is a vector, thus it has a direction. Therefore, you can change the velocity by changing direction. A great example of this is a ball on a string spinning at a constant speed, but it is continually changing direction, therefore, even though the speed is constant the velocity changes at every instant.
Is it possible to run round an oval running track at constant velocity?
No, it is not. At a constant speed, yes. But velocity has a direction component, and by running on (following) a curve, a change of direction (and, therefore, velocity) will have to be made. Again, note that speed can stay the same, but velocity has a direction vector associated with it that cannot be ignored.
What is the difference between a 9mm round and a .38?
Bullet diameter of a 9mm is .355; for a 38 it is .357. 38 case is longer. Additionally, a 9mm is designed to be used in a semi-automatic pistol, and a .38 is designed to be used in a revolver, although, there are a couple of revolvers that will chamber 9mm.
How does the tangential velocity of a planet relate to it orbiting around the sun?
The tangential velocity is equal to the circumference of the orbit divided by the time taken to go round once. For the Earth that is 2pi time 149.6 million kilometres divided by 365.25 days, which comes to 2.57 million km per day or 30 km/sec.
What is the maximum speed with which a 1200- car can round a turn of radius 72 on a flat road if the coefficient of static friction between tires and road is 0.65?
7
What is the maximum speed with which a 2500 kg car can round a turn of radius 60 m on a level road if the coefficient of static friction between tire and road is 7?
The maximum speed that a car can round a turn without slipping is given by the equation v = sqrt(μ * g * r), where μ is the coefficient of static friction, g is acceleration due to gravity, and r is the radius of the turn. Plugging in the values, v = sqrt(7 * 9.8 * 60) = 54.53 m/s. So, the car can round the turn at a maximum speed of approximately 54.53 m/s.
Would a merry go round have a changing velocity?
Yes, a merry-go-round would have a changing velocity because it is constantly changing direction as it rotates. The velocity of an object includes both speed and direction, so as the merry-go-round spins, its velocity is constantly changing.
When an object rolls over a surface the kind of friction that occurs is called round friction.?
The friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is typically less than sliding friction because the object's motion is smoother and involves less resistance from the surface.
If the correlation coefficient r is equal to 0.35 find the coefficient of nondetermination?
The coefficient of nondetermination is found by 1.00-r squared so 1.00-0.35X0.35 1.00-0.1225 0.8772 round it to 0.88
Why it is easier to roll a barrel on road than to pull it?
When we roll a barrel on the road, rolling friction acts in the direction opposite to the direction of rolling. In case of pulling, kinetic friction acts opposite to the direction in which the barrel moves. The coefficient of rolling friction is almost always less than the coefficient of kinetic friction. So therefore, in layman's terms, rolling friction is less than kinetic friction, therefore less resistance is faced by the barrel while rolling.
When an object rolls over a surface the kind of friction that occurred is called round friction True or false?
false it is rolling friction
True or false when an object rolls over a surface the kind of friction that occurs is called round friction?
False. The type of friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is caused by the deformation of the object and surface at the point of contact, which generates resistance that opposes the motion of the object.
How fast does air with a velocity pressure of 0.20 in w.g. move through a round duct?
The velocity of air flowing through a round duct can be calculated using the formula: Velocity = (2 * velocity pressure) / (air density). Given the velocity pressure of 0.20 in w.g., the air density needs to be known to determine the velocity.
You are standing on a merry-go-round that is in motion what forces is keeping you from flying off?
Friction. Friction is a resistance to motion.
What is the maximum speed with which a 1200-kg kg car can round a turn of radius 93.0m on a flat road if the coefficient of static friction between tires and road is 0.45?
The idea here is to: * Write an equation for the centripetal acceleration, using v squared / r. * Calculate the corresponding centripetal force, using Newton's Second Law (multiply the previous point by the mass). * Write an equation for the force of friction. * Equate the two forces, and solve.
Is a present between the surface of round object and surface where its move?
Friction
