They don't want to be killed or they are hiding
Answer:
oc
Explanation:
year 10 .May be this is the answer.
The answer is D. <span>d. Event 4 may cause a hurricane and Event 2 may cause a tornado.
Event 4, the difference in pressure cause by this will resulted in the air to start moving uncontrollably, which ending up in Hurricane
Event 2, this will create energy needed for thunderstorm to be formed which could lead to Tornado</span>
Answer:
See the answers below.
Explanation:
The cost of energy can be calculated by multiplying each given value, a dimensional analysis must be taken into account in order to calculate the total value of the cost in Rs.
![Cost=0.350[kW]*12[\frac{hr}{1day}]*30[days]*4.5[\frac{Rs}{kW*hr} ]=567[Rs]](https://tex.z-dn.net/?f=Cost%3D0.350%5BkW%5D%2A12%5B%5Cfrac%7Bhr%7D%7B1day%7D%5D%2A30%5Bdays%5D%2A4.5%5B%5Cfrac%7BRs%7D%7BkW%2Ahr%7D%20%5D%3D567%5BRs%5D)
The fuse can be calculated by knowing the amperage.
![P=V*I](https://tex.z-dn.net/?f=P%3DV%2AI)
where:
P = power = 350 [W]
V = voltage = 240 [V]
I = amperage [amp]
Now clearing I from the equation above:
![I=P/V\\I=350/240\\I=1.458[amp]](https://tex.z-dn.net/?f=I%3DP%2FV%5C%5CI%3D350%2F240%5C%5CI%3D1.458%5Bamp%5D)
The fuse should be larger than the current of the circuit, i.e. about 2 [amp]
The change in momentum of the ball is D) 1.8 kg m/s
Explanation:
The change in momentum of the ball is given by:
![\Delta p = m(v-u)](https://tex.z-dn.net/?f=%5CDelta%20p%20%3D%20m%28v-u%29)
where
m is the mass of the ball
v is the final velocity
u is the initial velocity
In order to calculate the change in momentum correctly, we have to correctly take into account the sign of the velocity. Taking the final direction of the ball as positive direction, we have:
u = -12 m/s is the initial velocity
v = +18 m/s is the final velocity (it changes sign because the direction has changed)
m = 0.060 kg is the mass of the ball
Solving the equation, we find the change in momentum of the ball:
![\Delta p = (0.060)(+18-(-12))=1.8 kg m/s](https://tex.z-dn.net/?f=%5CDelta%20p%20%3D%20%280.060%29%28%2B18-%28-12%29%29%3D1.8%20kg%20m%2Fs)
