Wave speed = frequency x wavelength
= 50 x 0.1
= 5 m/s
Hope this helps!
Answer:
Option e is correct
The heat required to increase the temperature of copper metal by 1 degree is 0.754 j
.
Explanation:
Given data:
specific heat of copper = 0.377 j/g.°C
Heat required to increase temperature = ?
Mass of copper = 2.00 g
Change in temperature = 1°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Q = m.c. ΔT
Q = 2 g× 0.377 j/g.°C × 1°C
Q = 0.754 j
The heat required to increase the temperature of copper metal by 1 degree is 0.754 j
.
Answer:
The density in g/cm3 is 1.9333(put a line above the 3's to show it's repeating).
And no it is not gold because the density of gold in g/cm3 is 19.3.
Explanation:
Divide the mass by the volume in order to get an object's Density.
so, 23.2 divided by 1.20 mm3
=1.93333333 g/cm3
That is the density then you find out the density of gold in grams per cubic centimeter, that is 19.3 g/cm3
For example, gold will always have a density of 19.3 g/cm3; if a mineral has a density other than that, it isn't gold.
There are no options but law of conservation of energy states that energy can’t be created or destroyed.
