Explanation:
It is given that,
The mass of bob, m = 77 kg
Length of the string, L = 10 m
Angle made by the string with the vertical, 
(a) Let T is the force exerted by the string on the pendulum. At equilibrium,
T = 755.63 N
The horizontal component of the force is given by,
The vertical component of the force is given by,
(b) Let a is the radial acceleration of the bob. It can be calculated as :
Hence, this is the required solution.
The answer is True.
you use it to solve or to better understand a problem and then solve it
Answer:
72mph/sec
Explanation:
The car goes from 100mph to 316mph in three seconds. Meaning it increases its speed by (316 - 100)mph in three seconds. That is 216 mph increase in three seconds. So, we divide the speed increase by the amount of time the increase occurred over. We get:
216mph / 3sec = 72mph/sec, our final answer
Hope it made sense. I would appreciate Brainliest, but no worries.
For both NPN and PNP this is true:
The base is between the collector and the emitter.
Answer:
Solar radiation may be converted directly into electricity by solar cells (photovoltaic cells). In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
