What is the product of vector and scalar?
The product of a vector and a scalar is a new vector whose magnitude is the product of the magnitude of the original vector and the scalar, and whose direction remains the same as the original vector if the scalar is positive or in the opposite direction if the scalar is negative.
Find the scalar multiple of a vector?
To find the scalar multiple of a vector, you multiply each component of the vector by the scalar. For example, if you have a vector v = (a, b, c) and you want to find 2v, you would multiply each component by 2 to get (2a, 2b, 2c).
If a quart of strawberries weigh 2 pounds how many quarts of strawberries would weigh .25 ton?
To convert pounds to tons, you need to divide by 2,000 since there are 2,000 pounds in a ton. Therefore, 0.25 tons is equal to 500 pounds. If a quart of strawberries weighs 2 pounds, then 500 pounds would be equal to 250 quarts of strawberries. So, 0.25 tons of strawberries would weigh 250 quarts.
What is meant by spin of the atomic particles as half and one?
The spin of atomic particles refers to an intrinsic angular momentum property they possess. When we say the spin is "half," it means the particle has spin quantum number 1/2, typical of fermions like electrons. When we say the spin is "one," it means the particle has spin quantum number 1, typical of bosons like photons.
How do you compare the units of work and kinetic energy?
Work is a measure of energy transferred to or from an object, while kinetic energy is the energy possessed by an object in motion. Work is measured in joules (J), which are also the units for kinetic energy. However, work involves the transfer of energy, while kinetic energy is the energy of motion possessed by an object.
