Answer:
The distance that separates the two particles is 7.42 cm.
Explanation:
Given;
the mass of each particle, m = 3 mg = 3 x 10⁻⁶ kg
the magnitude of charge of each particle, q = 6.0 nC
speed of each particle, v = 5.0 m/s
a = v/t
where;
a is the acceleration of the two particles
v is the final velocity
t is time
v = u + gt
5 = 0 + 9.8t
5 = 9.8t
t = 5/9.8
t = 0.51 s
a = v/t
a = 5/0.51 = 9.8 m/s²
Total force on the two particles = (2m)a = (2* 3 x 10⁻⁶)9.8
F = 5.88 x 10⁻⁵ N
Substitute in the value of F in the above equation and calculate r
where;
k is coulomb's constant = 8.99 x 10⁹ Nm²/c²
r is the distance of separation between the two particles
Therefore, the distance that separates the two particles at the instant when each has a speed of 5.0 m/s, is 7.42 cm.
Answer:
A conduct repeated trials and make sure the experiment can be replicated.
Explanation:
The answer to Willem's experiment are as follows;
A) The two other measurements Willem will require to calculate the specific heat capacity of copper are;
- The mass of the copper block
- The change in temperature of the copper block after heat is supplied.
B) The block must be well insulated to ensure no heat energy is lost to the surrounding by conduction, convection and radiation and hence, all heat supplied is used to effect a change in temperature in the copper block as intended.
C) If the block is poorly insulated, energy is lost and hence, the result would be too high because more energy would be consumed in the process.

Answer:
It will go on forever and won’t stop moving
Explanation:
I think it will travel forever and will be slow in the process it won’t stop is what I think
Actually Welcome to the Concept of the Ohms Law,
According to the Ohms law,
V = I*R, where, V = Voltage, I = Current, R = resistance,
so here given as, V = 240 V, I = 32 A,
so we get as, R = 240/32
R = 7.5 ohms,
===> The resistant R is ==> 7.5 ohms.
