We have to speed up the watch so we need to decrease time period of pendulum. So we hv to reduce the length.
The correct formula can be used to find the magnitude of the other initial vector is

What is vector?</h3>
- In mathematics and physics, the term "vector" is used informally to describe certain quantities that cannot be described by a single number or by a set of vector space elements.
- In the past, vectors were first used to represent quantities with both a magnitude and a direction, such as displacements, forces, and velocity, in geometry and physics (usually in mechanics). Similar to how distances, masses, and time are represented by real numbers, these quantities are represented by geometric vectors.
- In some circumstances, tuples—finite sequences of numbers with a definite length—are sometimes referred to as vectors.
The two vectors are given as A and B.
As per the question, the two vectors intersect each other perpendicularly
Hence, the angle between them is
The magnitude of the resultant is given as R.
From the parallelogram law of vector addition, the resultant R is calculated as

Question:
Suppose two initial vectors intersect at a right angle and form a resultant vector. The magnitudes of one initial vector, A, and the resultant vector, R, are given. Which formula can be used to find the magnitude of the other initial vector, B?
It state that the average kinetic energy from a gas particle depends only on the temperature of the gas
Answer:
3300 J
Explanation:
P = Q/t
Q = Pt = 110 * 30 = 3300 J
Ok you divide the force of friction by the applied force (11250/15000) and that gives the coefficient of friction, coefficient of friction is always between 0 and 1, when divided out you get 0.75 set that equal to the force of friction equation (Ff=(g)(m)(coefficient of friction)) so you get 11250=9.81(0.75)m and then you simplify to 11250/(9.81)(0.75) and you get 1529 kg with sig figs I’d say you can do 1530 kg, by the way the g is for acceleration produced by gravity which is 9.81 on earth.
