It is more likely to be a metal. This is because metals are good heat conductors whereas non metals tend to be poor heat conductors.
Answer:
is constant
Explanation:
Energy cannot be destroyed or created, but can transfer from places to places and in different forms.
(a) The acceleration of the salt shaker is 1.18 m/s².
(b) The distance traveled by the baseball player before coming to rest is 204.1 m.
<h3>
Acceleration of the salt shaker</h3>
The acceleration of the salt shaker at the given coefficient of kinetic friction is determined as follows;
a = μg
a = 0.12 x 9.8
a = 1.18 m/s²
Acceleration of the baseball player is calculated as follows;
a = μg
a = 0.4 x 9.8
a = 3.92 m/s²
<h3>Distance traveled by the baseball player</h3>
The distance traveled by the baseball player before coming to rest is calculated as follows;
v² = u² - 2as
0 = 40² - 2(3.92)s
0 = 1600 - 7.84s
7.84s = 1600
s = 204.1 m
The complete question is below:
A baseball player slides into third base with an initial speed of 40 m/s. If the coefficient of kinetic friction between the player and the ground is 0.40, how far does the player slide before coming to rest?

I believe the answer is 37cm. Hope this helps.
First and foremost, a photon is quantum of light. It is otherwise known as visible light and has a wavelength range of 400 to 700 nm. Moving waves are describable by their frequency (number of waves per second) and wavelengths.
A single photon can be considered unique from other photons only by its energy. In empty space (vacuum), all photons have the same speed or velocity.
The frequency of the electromagnetic vibration, we know as light, is given in units of Hertz. One hertz is equivalent to one vibration per second; it must be noted that the range of spectrum perceived by the eye extends from 4.3 x 10∧ 14 Hz in the red to about 7.5 x 10∧ 14 Hz in the violet.
