Answer:

True.

Explanation:

Energy can be given off by heat, a lot of heat can be a sign of a lot of energy. And a shorter wavelength the more energy, which I've learned in school.

A 1300 kg car starts at rest and rolls down a hill from a height of 10.0 m. It then moves across a

Makovka662 [10]

Answer:

0.51 m

Explanation:

Using the principle of conservation of energy, change in potential energy equals to the change in kinetic energy of the spring.

Kinetic energy, KE=½kx²

Where k is spring constant and x is the compression of spring

Potential energy, PE=mgh

Where g is acceleration due to gravity, h is height and m is mass

Equating KE=PE

mgh=½kx²

Making x the subject of formula

$x=\sqrt {\frac {2mgh}{k}}$

Substituting 9.81 m/s² for g, 1300 kg for m, 10m for h and 1000000 for k then

$x=\sqrt \frac {2*1300*9.81*10}{1000000}=0.50503465227646m\\x\approx 0.51 m$

A positive point charge Q is fixed on a very large horizontal frictionless tabletop. A second positive point charge q is release

UNO [17]

Answer:

As it moves farther and farther away from Q, it's speed will keep increasing.

Explanation:

This is so because the point charges are both positive charges and positive charges repel.

As the charges repel, they do so at an increasing speed.

The frequency of a wavelength ?

serious [3.7K]

Answer:

$f=0.1$

Explanation:

Use the equation:

$f=\frac{1}{T}$ (where T is the period)

$f=\frac{1}{9}$ (9 comes from the period of a full wavelength)

$f=0.1$
