How much power is needed to lift a 2000N object in 4.0s?
The power needed to lift a 2000N object in 4.0s can be calculated using the formula: Power = Work / Time. First, calculate the work done, which is Work = force x distance. Assuming distance is 1 meter (for simplicity), Work = 2000N x 1m = 2000 Joules. Then, Power = 2000J / 4s = 500 Watts. Therefore, 500 Watts of power is needed to lift a 2000N object in 4.0s.
If a force of 600N had acted over the same distance what would have been the gain in kinetic energy?
Work = Force * Distance Work = Change in Kinetic Energy Symbolically: W = Fd = ΔK Now, since the change in kinetic energy is an interval, then: ΔK = (K_final) - (K_initial) This difference indicates the gain or loss. As such, merely multiply 600N by the distance it travels through.
What really are balanced forces?
A balanced force is when two equal forces are applied on an object pushing both ways. Also they are equal forces acting on an object in opposite directions.When something isn't moving the forces are balanced, eg. Gravity pulls a table down but that table is pushed up by the floor or the ground it stands on so doesn't move.An UNbalanced force is needed for something to change movement or change direction, eg. a seesaw moving up and down because the forces aren't equal.A balanced force is a force equally opposed by another force in the opposite direction, meaning that they cancel out each other so the object does not move, unlike an unbalanced force, where the object will move because one force over powers the other.When something isn't moving the forces are balanced, eg. Gravity pulls a table down but that table is pushed up by the floor or the ground it stands on so doesn't move.An UNbalanced force is needed for something to change movement or change direction, eg. a seesaw moving up and down because the forces aren't equal.Unlike balanced forces, we say unbalanced forces when two forces acting on an object are not equal in size.When a number of forces act on a body simultaneously and the resultant of these forces is zero, then the forces are said to be balanced.Moment=distance from pivot to source of force x forceNm= m x NMoments on either side of an object must be equal for the object to balance.e.g on a see-saw someone who weighs 1000N sits 1m from the pivot, and someone who weighs 2000N sits 0.5m from the pivot on the other side of the see-saw will balance as in this situation, on both sides of the see- saw Nm=1000A balanced force is where forces on opposite sides of the object are the same net force (for example, 15 N and -15 N) which makes for the object being at rest. Balanced net force on an object makes for the object ALWAYS being at rest. Also it has to be even on both sides to be a balanced force -Keyaira PennieBalanced forces do not cause a change in motion. They are equal in size and opposite in direction.

How was the number zero invented?
It was made in roe in the early years about 2000n years ago
What force is needed to accelerate an elevator with a mass of 1000 kg upward at a rate of 2 m per second squared?
Weight of the elevator = 1000kg x -9.8m/s2 = -9800N Upward force acting on the elevator = 1000kg x 2m/s2 = 2000N Net force = upward force - weight of elevator = 2000N - (-9800N) = 11800N
Are there any triangular numbers that end in 000?
Yes, there are triangular numbers that end in 000. For example, 2,001,000 and 7,998,000. You can find a triangular number T that ends in 000 using the formula T = (1/2)(k)(k+1), where k is equal to any of the following: 2000n 2000n+1999 125(16n+11) 16(125n+39) and n is any positive integer.
How much force to apply to a piston with an area of 10 cm2 to lift an object weithing 2000n on a piston with an area of 50cm2?
400 N 400 N / 10cm2 = 2000 N / 50cm2
If a force of 600N had acted over the same distance what would have been the gain in kinetic energy?
Work = Force * Distance Work = Change in Kinetic Energy Symbolically: W = Fd = ΔK Now, since the change in kinetic energy is an interval, then: ΔK = (K_final) - (K_initial) This difference indicates the gain or loss. As such, merely multiply 600N by the distance it travels through.
Definition of Stress and strain?
Strain* A rubber band has a original length of 5cm and was pulled longer to 6cm. Thus 1cm difference and we divide difference in length with original length. = 1 divided by 5= 0.2 So in this case, Strain = 0.2 (Strain is a ratio and therefore no units.) Stress* Stress is the amount of pull and push force applied over a cross-sectional area and right angle to the action of the force. (The basic S.I. units of stress is N/m2) So, if you have a 20N force applied over an area of 10cm2 at right angle... Stress = load divided by area Stress = 20N divided by 0.01m (converting from cm to meter) Stress = 2000N/m2 Or Stress = 2000Pa = 2kPa Just remember that Strain* = lenght and Stress* = pressure.
What force keeps a bridge from breaking?
well im looking for that answer but havent quite found it but i got this.....The truss elements are subjected only to tensile and compressive loads, and thus are designed accordingly. Truss bridges are not intended to withstand the bending forces, and are best suitable for the straight alignments. A truss bridge is designed to endure extreme weights and also cover extended gaps.
