The angular speed in rpm will be 6. Angular speed is defined as the ratio of the revolution in the given time interval.
The rate of change of angulardisplacement is defined as angular speed.
ω = n/t
Where,
n is the number of revolution
t is the time
ω is the angular speed
ω = n/t
ω = 18/6
ω = 3 rpm
Hence,the angular speed in rpm will be 6 .

Answer:
The displacement of the particle after a time of 3.64 × 10⁻² s = 0.366 m
Explanation:
Given q = 19.6 μC = 19.6 × 10^-6 C
m = mass of the charge = 2.37 × 10^-5 kg
E = 668 N/C
We first calculate the force on the charge
F = Electric field × Charge = Eq = 668 × 19.6 × 10⁻⁶ = 0.0131 N
Then, using Newton's law of motion's F = ma
We can obtain the acceleration of the particle
0.0131 = 2.37 × 10⁻⁵ × a
a = 0.0131/(2.37 × 10⁻⁵) = 552.4 m/s²
Then, using the equations of motion, we can obtain the displacement of the charge after t = 3.64 × 10⁻² = 0.0364 s
u = initial velocity = 0 m/s (since the particle was initially at rest)
t = 0.0364 s
a = 552.4 m/s²
d = displacement of the particle = ?
d = ut + at²/2
d = (0)(0.0364) + (552.4)(0.0364²)/2 = 0 + 0.366 = 0.366 m
in scientific notation, how many micrograms make 1 kg
Answer:
10g
Explanation:
The experiment is about melting of tin. When solid tin is melted, it retains the amount of substance it originally has and we expect it to still be 10g.
Mass is the quantity or amount of matter contained in a substance. For most chemical processes, the law of conservation of matter is always succinctly observed.
The law states that "matter is neither created nor destroyed in a chemical reaction or process". Although melting is a phase change, we can adapt this law to the process. Owning to no loss of matter in the melting procedure, the amount of substance remains the same.
Therefore, we are left with about the same mass of substance we started with which is 10g.
Answer:
10g
Explanation:
As the Law of Conservation of Mass states that " Mass can neither be created nor be destroyed in a chemical reaction".
Though melting of tin isn't a chemical change, the same logic is applied here...
Hence,
The mass of tin will be 10 g itself...
