Answer:
F = m a = m v / t where v is the change in velocity in time t
F = p / t since m v is equal to p
F = 2.2 (kg m / s) / 1.1 s = 2 kg-m / s^2 = 2 N
Or you can use the impulse equation
The two Health and safety risk at the scene are:
1. To deal with Chemicals.
2. To deal with Electricity.
<h3>What are Healthy and safety risk?</h3>
The healthy and safety risk at the scene or office is described as safety hazards that has to be taken when employers are working in office in some mechanical or electrical workshops.
Employers need to e follow some healthy and safety risk while working in office like:
1. Chemicals : When employees have to handle harmful or dangerous chemicals as part of their work. To safety safe the must wear protective clothing.
2. Electrics - Electrical safety is an important issue in workplace , especially where there is a risk that heavy-duty equipment might cause electric shock.
These are some safety hazards employees must follow.

<span>The answer is transformer. They utilize
electromagnetic induction to generate current. This is only possible in
alternating current due to the differential increase and decrease of electrical
current that induces changes in magnetic flux in the coil. This varies the
magnetic flux of the primary coil that generates current in the secondary coil.</span>
The VI graph helps us to find Resistance.
- It was used by Ohm which is well known as ohms law.
Softball weigh around 180 grams or that would be 0.18 Kg. Basketball usually weighs around 22 ounce or 0.6 Kg. To compare the momentum of the two ball we have to use the formula of momentum which is p = mv. m for mass and v for velocity. let us assume both ball are travelling 2 m/s).
Softball. p = mv = (0.18 Kg)(2 m/s) = 0.36 Kg.m/s ( smaller momentum)
Basketball p = mv = (0.6 Kg)(2 m/s) = 1. 2 Kg.m/s (larger momentum
