Answer:

True but mostly false.

Explanation:

If you squint enough at night, you'd be able to see it. Otherwise it's not really possible.

a car is rolling backward when it hits the gas. after 8.25 s it is moving forward at 8.62m/s, and is 12.9m to the right of its s

MAXImum [283]

Answer: = . /

Explanation:

The acceleration is

= − 0

In our case, the initial velocity has minus sign.

Thus,

= − (−0) = + 0

Substituting

0 = 2 ( + 0 ) − = 2 + 0 2 −

Thus,

0 2 = 2 −

So,

0 = − = 8.62 − 12.9

8.25 = 7.06 m/s

Answer: = . /

How does Pascal's principle describe pressure throughout a fluid?

jarptica [38.1K]

Answer:

Uniform

Explanation:

The Pascal's principle states that a change in pressure applied to an enclosed fluid is transmitted unchanged to all parts of the fluid and to the container's wall.

This implies that there is no change in magnitude of pressure at every point of the fluid and the walls of the container. Hence you can say that pressure is equal in all directions at any point of the fluid.

A hockey puck with a mass of 0.18 kg is at rest on the horizontal frictionless surface of the rink. A player applies a horizonta

Leya [2.2K]

Hello!

$\large\boxed{0.018 N}$

Begin by finding the acceleration of the puck. Use the kinematic equation:

$d = v_{i} + \frac{1}{2}at^{2}$

The initial velocity is 0 m/s since the object was at rest, so we can rewrite the equation as:

$d = \frac{1}{2}at^{2}$

Plug in the given distance and time:

$1.25 = \frac{1}{2}a(5^{2})\\\\2.50 = 25a\\\\a = 0.1 m/s^{2}$

Find the net force using the formula F = m · a (Newton's Second Law)

F = 0.18 · 0.1

F = 0.018 N

The metal with the highest melting temperature is tungsten which melts at around 3400 K. What is the wavelength of the peak of t

alekssr [168]

Explanation:

It is given that, the metal with the highest melting temperature is tungsten which melts at around 3400 K, T = 3400 K

We need to find the wavelength of the peak of the black body distribution for this temperature. It can be calculated using Wein's displacement law as :

$\lambda\times T=k$
