a runner starts from rest and has an acceleration of 3 m/s^2. How fast is she running after 1.1 seconds
grigory [225]
Acceleration x time = velocity 

Since you're given acceleration and time, just plug the values into the equation. 

3\frac{m}{s^{2}} x 1.1 s = ? 

Solve that equation, and remember your velocity should be in m/s.

A 0.8 m length of wire is formed into a single turn, square loop in which there is a current of 12 A. The loop is placed in magn
rewona [7]

Answer:

0.073 N-m

Explanation:

i = 12 A, l = 0.8 m, B = 0.12 T

The circumference of the loop is 0.8 m.

Let r be the radius of the loop.

2 x 3.14 x r = 0.8

r = 0.127 m

Maximum Torque = i x A x B

Maximum Torque = 12 x 3.14 x 0.127 x 0.127 x 0.12 = 0.073 N-m

Which of these is most directly related to the mass of an object?
Anuta_ua [19.1K]
Weight is directly related to mass, but it also
depends on the local gravity.

Acceleration is directly related to mass, but it also
depends on the net force acting on the mass.

<span> <span> </span></span>Volume is directly related to mass, but it also
depends on the density of the object or sample.

Inertia is directly related to mass, and is completely determined
by the mass.  It doesn't depend on anything else, so this may be
the best choice.
