Lithium,
Electrons are 3
Protons are 3
Neutrons are 4
Answer:
The answer to your question is: 158 L
Explanation:
Rule of three
1 gal -------------------- 3.785 L
42 gal -------------------- x
x = (42 x 3.785) / 1
x = 158.97 L
When an acid and a base react together the products they form are an ionic compound or salt and water.
One by one.
<span>1) What
force (in newtons) is required to accelerate a body with a mass of 32
kilograms at a rate of 12 m/s2?
Data:
m = 32 kg
a = 12 m/s^2
Principle / formula: Secon Law of Newton, F = m*a
=> F = 32 kg * 12 m/s^2 = 384 N
2) If a body with a mass of 4 kg is moved
by a force of 20 N, what is the rate of its acceleration?
Data:
m = 4 kg
F = 20 N
a =?
Formula: F = m*a => a = F/m = 20N / 4kg = 5 m/s^2
3) A car with a
mass of 1,500 kg is traveling at a speed of 30 m/s. What force must be
applied to stop the car in 3 seconds?
Data:
m = 1500 kg
Vo = 30 m/s
Vf =?
t = 3 seconds
F = ?
Formulas:
F = m*a
a = [Vf - Vo]/t
=> a = [30m/s - 0] / 3 s = 30m/s / 3s = 10 m/s^2
=> F = 1500 kg * 10 m/s^2 = 15,000 N
4) If a suitcase has a mass of 20 kg,
what is the force of gravity acting on it?
F = m * g = 20 kg * 9.8 m/s^2 = 196 N
5) On the moon, what would be
the force of gravity acting on an object that has a mass of 7 kg?
Use g in the moon 1.625 m/s^2
F = m * g = 7 kg * 1.625 m/s^2 = 11.735 N
6) On
earth, what is a child’s mass if the force of gravity on the child’s
body is 100 N?
F = m * g => m = F / g = 100N / 9.8 m/s^2 = 10.2 kg
