Answer:
28+49
Step-by-step explanation:
Answer:
Step-by-step explanation:
From the function, y = cos (3x)
Inputting values of x (horizontal axis), x = pi
y = cos (3 × pi)
= -1 ( remember you are dealing with values in radians not degree)
So now graph 1 and 3 have the same values. So inputting, x = pi/2 into the function, y = cos (3x)
= cos ((3 × pi)/2)
= 0
View the correct graph below.
15 + 16 + 15 + 8 + 6 = 60 divided by 5 = 12
Answer is D
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.

Answer:
4 = x
Step-by-step explanation:
x³ - 5 = 59 Add five to both sides of the equation.
x³ = 64 Now find the cubed root of 64
∛64 = 4
x = 4
