Answer:
0.284 A
Explanation:
We are given that
Mass,m=0.246 kg
Potential difference,V=1.50 V
Efficiency=30.6%
Time,t=7.88 s
Initial speed=0
Speed,v=2.89 m/s
Kinetic energy=
Using the formula
30.6% of Electric energy=K.E
Answer:
Option D)Potential energy becomes kinetic energy between points P and Q.
Explanation:
Answer:
SNR which stand for signal to noise ratio is a ratio that is calculated to compare the disired signal level and background noise level
Explanation:
SNR which stand for signal to noise ratio is a ratio that is calculated to compare the disired signal level and background noise level. It is expressed in db i.e. decibel. and ratio of 1:1 shows more signal level than noise.
generally signal with 20 db is considered as good SNR value while 18 db around SNR is good for data.
Answer:
775 grams of ice
Explanation:
Heat loss by patient = heat gained by ice
Heat loss by patient = mass×specific heat capacity×(initial temperature - final temperature) = 62×4200×(40-39) = 260,400J
Heat gained by ice = mass × specific latent heat of fusion of ice = m×336000 = 336000m J
336000m = 260,400
m = 260400/336000 = 0.775kg = 0.775×1000 grams = 775 grams of ice
