How much does the speed increase of an object on a airtrack?
According to the speed of the aircraft on which the object is loaded
If a force of 300N is exerted upon a 60kg mass for 4 seconds how much impulse does the mass experience?
Impulse = (force) x (time) = 300 x 4 = 1,200kgm-meter/sec.The mass of the object doesn't matter. (However, if you want to know the change in its linear momentum, it's equal to the impulse.)
How much centripetal force is needed by a body moving in uniform circular motion if the mass is doubled?
If the mass is doubled then the force needed is also doubled,according to the equation F=MV2/R
What would be the momentum of a passenger bus if its velocity were doubled?
a) doubled b) tripled c) doubled (assuming the engine is used to bring it back to the same speed) d) quadrupled e) halved
When a hot object is placed in contact with a cooler object the hot object warms a cooler one can you say it loses as much temperature as the cooler one gains?
No. One object will lose as much HEAT as the other gains. The change in temperature, on the other hand, will depend on the masses involved and on their heat capacity. It is even possible that one object's temperature reduces, while the other doesn't increase at all - for example, when ice melts.
If the liner dimensions of an object are doubled how much dose the total area increase?
If the linear dimensions of a square or a rectangle are doubled, the area of the object will be quadrupled.
If each side of a rhombus is doubled how much times will it's area increase?
It will increase to four times as much.
How much will the volume of a rectangular prism increase if its length width and height are doubled?
Because the volume of a rectangular prism is the product of its length, width, and height, if these linear measures are doubled, the volume will increase by a factor of 23 = 8.
If the standard deviation is doubled what will be the effect on the confidence interval?
The confidence intervals will increase. How much it will increase depends on whether the underlying probability model is additive or multiplicative.
How much does the speed increase of an object on a airtrack?
According to the speed of the aircraft on which the object is loaded
How much did the US increase in land size with the Louisiana Purchase in 1803?
it doubled in size
What is the effect on the area of a trapezoid if a base is doubled?
The area increases, but there's no way to say by how much in general. The percent increase is different in different cases.
If a force of 300N is exerted upon a 60kg mass for 4 seconds how much impulse does the mass experience?
Impulse = (force) x (time) = 300 x 4 = 1,200kgm-meter/sec.The mass of the object doesn't matter. (However, if you want to know the change in its linear momentum, it's equal to the impulse.)
How much does the surface area increase?
It will increase by a factor of 4; in other words, it will be 4 times greater. Given that all sides of a cube are of equal dimension, I will call this variable dimension x. The surface area is, therefore, x2. If the side of the cube is doubled (2x), then the surface area would be (2x)(2x) = (2x)2 = 4x2. So: x --> 2x (the side length is doubled) x2 --> 4x2 (the surface area is quadrupled)
What is a impulse item?
an impulse item is something attractive that you buy without much thought :)
How much is 60 doubled?
120
What is having made twice as much?
doubled
