Is resistance a vector?
A vector quantity is one that has a magnitude (a number), and a direction. No, resistance is not a vector quantity; it is a scalar quantity (only magnitude).
The horizontal and vertical components of the initial velocity of a tennis ball are 18.2 ms and 21.3 ms respectively what is the magnitude of the initial velocity of the ball?
To take the magnitude of the velocity you will need to square both the horizontal and vertical components and then take the square root of their sum. So: V=(Vx2+Vy2)1/2
A 125.0 kg box is pushed by a horizontal force F at constant speed up a frictionless ramp which makes an angle of 25.0 deg with the horizontal Find the magnitude of the applied force F?
its really easy
How is the horizontal component of velocity for a projectile affected by the vertical component?
The horizontal component of velocity for a projectile is not affected by the vertical component at all. Horizontal component is measured as xcos(theta) Vertical component is measured as xsin(theta) Whereas theta is the angle, and x is the magnitude, or initial speed.
Is the momentum of the car travelling north different from the one of the same car when it travels south at the same speed?
Momentum is a vector. This means it has magnitude and direction. The magnitude will be the same. But the sign will be different. If north is positive, south will be negative. This is the only difference.
What is the horizontal component of a vector whose magnitude is 70 and whose direction relative to the horizontal is 20?
A vector with magnitude = 70 , directed 20° above or below horizontal,has a horizontal component of70 cos(20°) = 65.778 (rounded)
Is resistance a vector?
A vector quantity is one that has a magnitude (a number), and a direction. No, resistance is not a vector quantity; it is a scalar quantity (only magnitude).
How do you find the magnitude of the horizontal components of forces?
Find an expression for the magnitude of the horizontal force in the figure for which does not slip either up or down along the wedge. All surfaces are frictionless.
A 100kg man is hanging 5m above the horizontal ground.What magnitude of weight of the man?
The magnitude of the weight of the man is 980N.
What is the horizontal distance formula?
The answer depends on the context: If you have a distance vector of magnitude V, that is inclined at an angle q to the horizontal, then the horizontal distance is V*cos(q).
The relationship between resistance and conductors is?
ALL resistance are conductors. just the magnitude value changes
Which step will the ball hit first if A ball rolls at the top of a stairway with a horizontal velocity of magnitude 5.0fts the are 8.0 in high and 8.0 in wide?

What is plotted on the horizontal axis of an H-R diagram?
If you mean a Hertzsprung-Russell Diagram, which plots stars color, temperature, and absolute magnitude (see related link), then it looks like color and spectral class (temperature) are plotted on horizontal, and Absolute Magnitude/Lumenoscity are plotted on the vertical.
What is the relation between internal resistance and load resistance when current is constant in the circute?
The total resistance of a circuit is the sum of the supply's internal resistance and its load resistance, because they are in series with each other. This is true regardless of the magnitude of, or the variation in, the current.
How do you plot a trigonometry graph?
You plot the magnitude of the angle along the horizontal axis and the value of the trigonometric ratio on the vertical axis.
The horizontal and vertical components of the initial velocity of a tennis ball are 18.2 ms and 21.3 ms respectively what is the magnitude of the initial velocity of the ball?
To take the magnitude of the velocity you will need to square both the horizontal and vertical components and then take the square root of their sum. So: V=(Vx2+Vy2)1/2
A rope exerts a force of magnitude 21 N at an angle 31 deg above the horizontal on a box at rest on a horizontal floor?
A rope exerts a force of magnitude 21 N, at an angle 31 deg above the horizontal, on a box at rest on a horizontal floor. The coefficients of friction between the box and floor are Us = 0.55 and UK = 0.50. The box remains at rest. Determine the smallest possible mass of the box. this is the full question thanks for any help! :)
