Answer:
The ratio of water to flour needed to make tortillas, which is 3 : 4
Explanation:
100 w = 75 f
w/f = 75/100 = 3/4
Only put ciilant into ur radiator when the engine is cool (D)
Answer:
W=2 MW
Explanation:
Given that
COP= 2.5
Heat extracted from 85°C
Qa= 5 MW
Lets heat supplied at 150°C = Qr
The power input to heat pump = W
From first law of thermodynamics
Qr= Qa+ W
We know that COP of heat pump given as



W=2 MW
For Carnot heat pump


2.5 T₂ - 895= T₂
T₂=596.66 K
T₂=323.6 °C
Answer:

Explanation:
The position of each point are the following:

Since the three objects report charges with same sign, then, net force has a repulsive nature. The net force experimented by point charge A is:
