Answer:

C. Electronic charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.

Explanation:

All the electric charges have electric field in the region surrounding them

This electric field is given as

E = \frac{kq}{r^2}

above formula is the electric field due to a point charge in the surrounding region of it.

Now due to this electric field when other charges comes into this region they will experience electric force on them which is given as

F = qE

due to above reason two charges either attract or repel each other

so correct answer will be

C. Electronic charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.

Helga [31]

Answer:3.23 m/s^2

Explanation:

Given

\mu_s =0.330

Frictional Force is balanced by force due to car acceleration

Frictional force F_s

F_s=ma_{min}

\mu_sN=ma_{min}

\mu_s\cdot mg=ma_{min}

a_{min}=\mu_s \cdot g=0.330\times 9.8=3.23 m/s^2

If you wish to warm 100 kg of water by 20°C for your bath, how much heat is required? (Give your answer in calories and joules.)
taurus [48]
Q = mcθ

Where m = mass of water in kg.
c = specific heat capacity in kJ/kg⁰C, c for water = 4200 kJ/kg⁰C
θ = temperature rise in ⁰C

Q = 100*4200* 20    Note here the temperature rise is 20 ⁰C
Q = 8 400 000 J

In calories,  4.2 J = 1 Calorie
=  8 400 000 / 4.2   = 200 000

Q = 200 000 Calories
