B: an increase in acceleration caused an increase in force.
This is based on the concept of force on an object.
Now, formula for force is commonly known as;
Force = mass × acceleration
Now, mass and acceleration are the input values that make the output which is the Force to either increase or decrease.
- Now, for the line of dominoes to fall, it means that the force was so overwhelming that the dominoes couldn't resist it.
Now, this output which is the force became so much as a result of the increase in acceleration of the motion that triggered its movement.
Moreover, the force is directly proportional to the acceleration!
Thus, we can say that an increase in acceleration caused an increase in force.

The magnitude and direction of the force on the charge is -12 N opposite the electric field
To calculate the force on a charge in an electric field, we make use of the formula below.
<u>Formula</u>
F = E×Q .......................... Equation 1
Where:
- F = Force on the charge
- E = Electric Field
- Q = charge
From the question,
Given:
Substitute these values into equation 1
Note: The negative sign indicates that the force is in the direction negative of the electric field.
Hence, The magnitude and direction of the force on the charge is -12 N opposite the electric field

Answer:
a) 1.34 Volts
b) 3.08 W
c) 2.68 W
Explanation:
Given:
Emf of the cell, E = 1.54 V
current, i = 2.0 A
internal resistance, r = 0.100Ω
(a) Terminal voltage (V) = E - v
where,
v is the potential difference across the resistance 'r'
now,
according to the Ohm's Law, we have
v = i × r
substituting the values in the above equation we get
v = 2.0 × 0.100 = 0.2 Volts
thus,
Terminal voltage (V) = (1.54 - 0.2) = 1.34 V
(b) Now, the Total power (P) is given as
P = E × i = (1.54 × 2.0) = 3.08 W
(c) Power into its load = [terminal voltage, v] * i
= (1.34 × 2.0) = 2.68 W
C.) <span>The total mass of an object can be assumed to be focused at one point, which is called its center of "Mass"

The acceleration of the mass down the plane is determined as (4mg sinθ)/(3mr²).
<h3>Conservation of angular momentum</h3>
The acceleration of the mass down the plane is determined by applying the principle of conservation of angular momentum.
Fr = Iα
where;
- F is weight of the object parallel to the plane
- r is the radius of the flywheel
- I is moment of inertia
- α is angular acceleration
(mg sinθ)r = Iα
(mg sinθ)r = I(ar)
(mg sinθ) = I(a)
Thus, the acceleration of the mass down the plane is determined as (4mg sinθ)/(3mr²).
