Answer:
It’s 7 hours
Explanation:
You have to use the formula your teacher has given to you plug in the numbers then solve be sure to use a calculator made for physics it helps a lot :)
Answer:
The magnitude of the acceleration of the tip of the minute hand of the clock
.
Explanation:
Given that,
Length of minute hand = 0.55 m
Length of hour hand = 0.26 m
The time taken by the minute hand to complete one revelation is

We need to calculate the angular frequency
Using formula of angular frequency

Put the value into the formula


We need to calculate the magnitude of the acceleration of the tip of the minute hand of the clock
Using formula of acceleration

Put the value into the formula


Hence, The magnitude of the acceleration of the tip of the minute hand of the clock
.
Is that a question? If it is not what its the question?
Explanation:
Basaltic lava
Basaltic lava generally takes two distinct forms known by the Hawaiian terms pahoehoe and aa. Pahoehoe has a smooth wavy surface that resembles twisted rope. It advances by extruding molten toes of lava beneath a thin, flexible crust. As it travels pahoehoe lava often changes to blocky flows called aa.
Answer:
Explanation: When the electrons move in another direction, they convert this chemical potential energy to electricity in the circuit, thus discharging the battery. So, the battery is all potential energy.
