Answer:
A heterogeneous mixture is simply any mixture that is not uniform in composition - it's a non-uniform mixture of smaller constituent parts.
Explanation:
Thinking the small glass bead as a single point charge, the electric field generated by it is given by
![E(r) = k_e \frac{Q}{r^2}](https://tex.z-dn.net/?f=E%28r%29%20%3D%20k_e%20%20%5Cfrac%7BQ%7D%7Br%5E2%7D%20)
where
![k_e = 8.99 \cdot 10^9 N m^2 C^{-2}](https://tex.z-dn.net/?f=k_e%20%3D%208.99%20%5Ccdot%2010%5E9%20N%20m%5E2%20C%5E%7B-2%7D%20)
is the Coulomb's constant
![Q=8.0 nC=8.0 \cdot 10^{-9} C](https://tex.z-dn.net/?f=Q%3D8.0%20nC%3D8.0%20%5Ccdot%2010%5E%7B-9%7D%20C)
is the charge of the bead
![r=3.0 cm=0.03 m](https://tex.z-dn.net/?f=r%3D3.0%20cm%3D0.03%20m)
is the distance at which we calculate the field.
Using these data, we find:
Metals tend to readily lose electrons and form cations. Most of them react with atmospheric oxygen to form metal oxides. However, different metals have different reactivities towards oxygen (unreactive metals such as gold and platinum do not readily form oxides when exposed to air
The current made by the circuit produce this effect by generating a magnetic field that attracts the car magnetically to the crane lift and is denoted as option C.
<h3>What is a Crane?</h3>
This is a machine which is used to lift and lower objects which are most times heavy.
It employs the use of magnetic force as it is generated when the button is switched on in this scenario.

Answer:
0.1m/s²
Explanation:
Using the equation of motion
V = u+at
V is the final speed = 0.9m/s
Initial speed u = 0.5m/s
Time = 4secs
Get the acceleration
0.9 = 0 5+4a
0.9-0.5 = 4a
0.4 = 4a
a = 0.4/4
a = 0.1m/s²
Hence the acceleration is 0.1m/s²
