30+30=60+30=90
please my answer
It equals -4
y=-4 because you calculate 2-38 and then dividing by 9 you can check it on google
I am pretty sure b. is right. This is because 87 is not prime
The answer is 1/3.
To get to this conclusion you must halve both the numerator and the denominator until you reach a point where each number can no longer be halved.
32/96

Answer:
The magnitude of the electric force between these two objects
will be: 181.274 N.
i.e. F
N
Step-by-step explanation:
As
Two object accumulated a charge of 4.5 μC and another a charge of 2.8 μC.
so
q₁ = 4.5 μC = 4.5 × 10⁻⁶ C
q₂ = 2.8 μC = 2.8 × 10⁻⁶ C
separated distance = d = 2.5 cm
Calculating the magnitude of the force between two charged objects using the formula:


∵ 
∵

Therefore, the magnitude of the electric force between these two objects will be: 181.274 N.
i.e. F
