Answer:
a) equal 1, b) less than 1
Explanation:
a) the electric force is given by
Fe = q E
The charge of the electron and proton has the same value, that of the proton is positive and that of the electron is negative
Proton
Fp = qE
Electron
Fe = - q E
Fp / Fe = -1
If we do not take into account the sign the relationship is equal to one (1)
b) to calculate the force we use Newton's second law
F = ma
qE = m a
a = q E / m
The mass of the proton much greater than the mass of the electron
ap = q E / 
ae = - q E / 
ap / ae = /
= /1600 =1/1600
It is much smaller than 1

Answer:
A and C is about 12 cm away from each other.
Explanation:
The sample's density with respect to the volume it displaces is equal to: C. 0. 60 g/mL
<u>Given the following data:</u>
To calculate the sample's density:
First of all, we would determine the volume displaced by the sample;
Volume displaced = 3 mL
Density can be defined as mass all over the volume of an object. Thus, density is mass per unit volume of an object.
Mathematically, the density of a substance is given by the formula;
Substituting the given parameters into the formula, we have;
Density = 0.60 g/mL

Answer:
a) 0.124 m
b) 0.93 ms⁻¹
c) 0.5 k A² cos ² ( ωt )
Explanation:
1) Potential energy = U = 0.5 k A² , where A is the amplitude and k = 850 N/m is the spring constant.
0.5 ( 850) (A² ) = 6.5
⇒ A = 0.124 m = Amplitude.
b) From energy conservation, 0.5 m v² = 6.5
⇒ speed = v = 0.93 ms⁻¹
c) If x = A cos ωt ,
Potential energy = 0.5 k A² = 0.5 k A² cos ² ( ωt )
