Answer: uhhhhhhh what is this for?
Explanation i so confused
Answer:
The angular acceleration required is 0.1765 rad/ 
Explanation:
The radius of the bicycle wheel has a radius of 0.42 m.
The acceleration is for time, t = 6.8 seconds.
Initial angular velocity is given as
= 5.5 rad/s
Final angular velocity is given as
= 6.7 rad/s
Therefore from the formula for angular speed we get
=
+ (
t), where t is the time in seconds.
Therefore we get
6.7 = 5.5 + (6.8 ×
)
Therefore we get the angular acceleration,
= 
The angular acceleration required is 0.1765 rad/

Answer: 8Ω
Explanation:
Since there are two resistors of 4Ω
connected in series, the total resistance (Rtotal) of the circuit is the sum of each resistance.
i.e Rtotal = R1 + R2
R1 = 4Ω
R2 = 4Ω
Rtotal = ?
Rtotal = 4Ω + 4Ω
Rtotal = 8Ω
Thus, the total resistance of the circuit is 8Ω
Answer:
(a) warm air is forced upward where it cools;
(c) cumulonimbus or nimbo-stratus clouds form
(d) thunderstorms with heavy showers and gusty winds occur"
(b) air cools and sinks, pressure rises, rain stops;
Explanation:
- A cold for front is a denser air , as that forms under the warmer and lighter air mass and this causes a low pressure along the cold form and thus causes the formation of a thunderstorm where enough moisture is present and drop in temperature occurs and in the northern hemisphere the cold front shifts the winds to from the southwest to northwest clockwise.
