Explanation:
F = m a
F= 4.0×4.0
F= 16 N

F= ma
25= m × 4.998
m= 25/4.998
m= 5.002 kg

F=ma
53= 3 × a
a= 53/3
a= 17.666 m/s
Answer
-8.67× 10^6 N/C
Explanation:
The Electric Field is defined as force per unit charge.
E = Q/ 4π£r2
Qv= −6.5 μCm3
Qv = Q/ V= Q/ 4/3 πr3
Hence Q = 4/3 πr3 × Qv
Hence E = 4/3 πr3 × Qv / 4π£r2= Qvr/3£
−6.5 μ × 4/ 3×8.854 ×10^-12
-6.5 × 4 × 10^6/3 = -8.67× 10^6 N/C
Note: £ = 8.854×10^-12m/F
is the permittivity of free space
Qv is the charge per unit volume
V is volume and volume
<span>If you are looking for a substance that will easily dissolve in water, you should look for a substance with which properties? it is b. high solubility
</span>
PLASTICITY, the MALLEABILITY of the body; extent to which they will absorb water after firing; and SHRINKAGE the extent of revolution in size of a body as water is removed.
There you go!
