What is a acute angle in geometry?
acute angle IS SMALLER tHAN a Right Angle so it is Graeater than 0degree but Smaller than 90degree
How do you find resultant velocity?
When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.
What is the effect of increasing the angle between the strings on the resultant?
It is difficult to answer the question with any degree of certainty because there is no information on what the strings are meant to be doing, and to what. A likely answer is that the resultant will be a smaller force.
What is the result of multiplying vector components by a scalar?
If the scalar is > 1 the resultant vector will be larger and in the same direction. = 1 the resultant vector will be the same as the original vector. between 0 and 1 the resultant vector will be smaller and in the same direction. = 0 the resultant vector will be null. If the scalar is less than 0, then the pattern will be the same as above except that the direction of the resultant will be reversed.
How do you find the resulting velocity?
When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.
Can the magnitude of a resultant vector ever be less than the magnitude of one of its components?
Yes, if the two vectors are at a sufficiently large obtuse angle.The law of cosines gives the size of the resultant.If C = A + B, where A, B, C are vectors, then C is the "resultant."The law of cosines says, he magnitudes, A,B,C, are related as follows,C2=A2+B2+2AB cosine(theta),where theta is the angle between the vectors A and B. When theta is zero, then C has the maximum length, equal to the lengths of A and B added. When theta is 180 degrees, then C has the minimum length of the difference of the length of A and of B. Somewhere in between, the length of C will equal the length of the longer component and for larger angles be smaller.To be specific, suppose that A is the longer of the two, then the resultant, C, has the same length as A at one special angle which we will call theta*.A2=A2+B2+2AB cosine(theta*)cosine(theta*)=-B/(2A).The answer to the question is then, that for angles greater than theta* the resultant is smaller than the larger component. (Greater means, of course, greater than theta* and up to 360-theta*.)Note that if we ask whether the resultant can be smaller than the smaller of the two component vectors, then the answer is again yes and the above equation holds true when A is the smaller with the condition that it is not smaller than half the length of B. When the smaller vector is less than half the length of the larger component, then the resultant may equal the length of the larger but can never be made equal to the length of the smaller component.
What is the resultant force if the first force has an upward vector and the second force has a downward vector?
If the two vectors are directly opposite each other, then subtract the smaller one from the larger one and that will be your resultant force. For example, if the force downwards is 5 N and the force upwards is 2 N, the resultant force is 3 N downwards. If the one or both of the two vectors are angled, you need to replace the angled vectors with two right-angled vectors and then add those to create the resultant vectors.
What is the smallest unit of a polymer called?
The basic building block for a polymer is a monomer which are rather smaller than the resultant polymer.
Is having your arms closer together easier for pull ups or harder?
Having your arms wider apart will yield a smaller magnitude than if your arms were closer together. A resultant with a smaller magnitude means less force to counter your weight, hence a harder pull-up
Can a vector have a component greater than its magnitude in higher level physics?
yeah, it can. for example consider two antiparallel vectors of magnitude 5,3 whose resultant is 2, which is smaller than both components.....
Can the resultant magnitude of 2 vectors be smaller than either of the vectors?
Yes. As an extreme example, if you add two vectors of the same magnitude, which point in the opposite direction, you get a vector of magnitude zero as a result.
Does a smaller object with the same force will accelerate the same than a larger object?
The smaller object will have a larger acceleration than the larger object. This is because, from Newton's second law, the acceleration of a body is given by: a = F/m where a is acceleration F is resultant force and m is mass F is constant, so acceleration is inversely proportional to mass. Hence, the smaller object will have a larger acceleration.
