Answer:
There is no friction because of the mass.
Explanation:
The bigger box ran out of force to move so it hit the smaller box. (im in 7th grade and have the answer key)
Explanation:
It is known that relation between Gibb's free energy and equilibrium or reaction quotient is as follows.
..... (1)
At equilibrium, 
= 0. Also, Q = K this means that reaction is at equilibrium.
Therefore, formula in equation (1) will become as follows.
....... (2)
It is known that for a sparingly soluble salt, K = 
Thus, equation (2) will become as follows.
....... (3)
So, when value of increases then there will be decrease in the value of 
according to equation (3).
Hence, we can conclude that the calculated value of 
would be too big.
Answer:
28ºC
Explanation:
Formula for converting Fahrenheit to Celsius is (°F − 32) × 5/9 = °C
(82 − 32) × 5/9 = x
(50) × 5/9 = x
27.777...ºC = x
x ≈ 28ºC
Answer:
The units of both types of energy are Joule (kg × m² × s⁻²).
Explanation:
Step 1: Show the units of kinetic energy
The equation for kinetic energy is:
K = 1/2 × m × v²
where,
m: mass
v: speed
The units are:
K = 1/2 × m × v²
[K] = kg × (m/s)²
[K] = kg × m² × s⁻² = J
Step 2: Show the units of gravitational potential energy
The equation for gravitational potential energy is:
G = m × g × h
where,
m: mass
g: gravity
h: height
The units are:
G = m × g × h
[G] = kg × m/s² × m
[G] = kg × m² × s⁻² = J
