Momentum before the hit:
p = mv = 0.01 * 300 + 1 * 0
Momentum after the hit:
p = 0.01 * 150 + 1 * v
Momentum is conserved:
0.01 * 300 = 0.01 * 150 + v
3 = 1.5 + v
v = 1.5
The velocity of the block after the collision is 1.5 m/s.
If a = 2.0 cm, b = 5.0 cm, and i = 20 a, 6.0 μt is the magnitude of the magnetic field at the point p, So the correct option is (a).
The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.

i 
/ 
= μ i / 
As, is moving down and is moving up so,
- = (μ i / ) - [μ i / ]
- = μ i 24 / 
- = 
- = 5.98×
T ≈ 6μT
Therefore, 6.0 μt is the magnitude of the magnetic field .

A Safety Data Sheet (SDS) provides even more information on chemicals than a label: True.
<h3>What is a
Safety Data Sheet (
SDS)?</h3>
A Safety Data Sheet (SDS) can be defined as a text-based document (bulletin) that is developed to provide more information with respect to the chemical and physical properties of a chemical compound, substance or equipment such as:
Additionally, a Safety Data Sheet (SDS) contains information on the potential health hazards and safety precautions for proper use, handling, storage and transportation of a chemical compound, substance or equipment.
In conclusion, we can deduce that a Safety Data Sheet (SDS) provides even more information on chemicals than a label, which only contains lesser information about a product.

Answer:
300N
Explanation:
Given parameters:
Mass of car = 1500kg
Initial velocity = 0m/s
Distance covered = 45m
Time = 15s
Unknown:
Net force applied = ?
Solution:
From Newton's second law:
Force = mass x acceleration
Force = mass x 
v is the final velocity
u is the initial velocity
t is the time taken
Final velocity = 
=3m/s
Force = 1500 x 
= 300N
ANSWER:
C) as the electrons are pushed more by the battery, they move faster through the circuit
EXPLANATION:
Electrons move very slowly. When we supply voltage the current through a wire moves which causes each electron to move in the direction of the flow of current, the electrons which were in random motions previously now move in one direction which is the direction of current,the more we supply the current the faster electrons will move in the circuit,which will cause the current to increase with increase in voltage.
