The answer to this question is letter A. 50. Those who are not too familiar with the different formulas that are used in physics may have no idea how this is the correct answer. It is best to check out the given. The formula that will be used for this is F1D1=F2D2. 200N (20)/50. The answer to...
The correct answer is option C
When turning a door the turning effect of a force on a door is greater at a point far away from the hinges and perpendicular to the door. The turning effect of a pivot is known as the moment about that point. The moment of a force is a measure of its turning...
The correct answer to this question is B, 160NCM anticlockwise. This question deals with forces and moment. The metric rule of this question is uniform in the weight act. This uniformity creates an anticlockwise moment. The 4.0N weight is downward at one end, creating a clockwise...
PH3, otherwise known as phosphine and is quite toxic and flammable, forms a dipole-dipole because it is a polar molecule. We know it is polar because it has a lone pair and therefore its geometry is non-symmetrical as predicted by the VSEPR model.
Nonpolar molecules have a symmetrical...
The correct answer to this question is B.
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. Gravity is very important to us. We could not live on Earth without it. The sun's...
Regarding the system below, the statement that the total linear momentum is constant would be true. The linear momentum of a system remains constant provided that negligible amount of energy is lost or is converted into other forms.
The momentum of any object is related to the...
A force is a push or pull, it is true
