Answer:
Explanation:
Given parameters:
Electrical energy = 18J
Quantity of charge Q = 12C
Unknown:
Voltage = ?
Solution:
The expression of electrical potential energy is given as:
Electrical potential energy = c v²
c is the quantity of charge
v is the voltage
18 = x 12 x v²
18 = 6v²
v² = 3
v = 1.7v
The correct answer is: Angular velocity = 
rad/s
Explanation:
The angular velocity is given as:
ω =
--- (1)
Where T = 165 * (365 days) * (24 hours/day) * (60 minutes/hour) * (60 seconds/minute) = 5203440000 s
Plug in the value in (1):
ω =
rad/s
Explanation:
The angular velocity is given as:
ω =
Where T = 165 * (365 days) * (24 hours/day) * (60 minutes/hour) * (60 seconds/minute) = 5203440000 s
Plug in the value in (1):
ω =
Answer:
(a). The average acceleration during segment A is 2 m/s²
(b). The average acceleration during segment B is zero.
(c). The average acceleration during segment C is 4 m/s².
Explanation:
Given that,
A snowmobile moves according to the velocity-time graph ,
(a), We need to calculate the average acceleration during segment A
Using formula of average acceleration
Where, = initial velocity
=final velocity
= initial time
=final time
Put the value into the formula
(b). We need to calculate the average acceleration during segment B
Using formula of average acceleration
Put the value into the formula
(c). We need to calculate the average acceleration during segment C
Using formula of average acceleration
Put the value into the formula
Hence, (a). The average acceleration during segment A is 2 m/s²
(b). The average acceleration during segment B is zero.
(c). The average acceleration during segment C is 4 m/s².
