Normally you would just use m*c*delta T. But the c is the same in both cases, so you need just use m*deltaT
Givens
25 degrees
m = ?
T = 25
t = final temp = 75
93 degrees
m = 250
T = 93
t = final temp = 75
Solution
(t - 25)*m = (93 - t) * 250 Remove the brackets
75*m - 25m = 93*250 - 250*75 Combine the right
m(75 - 25) = 23250 - 250*75
50 m = 23250 - 18750 Combine
50 m = 4500 Divide both sides by 50
50*m/50 = 4500/50
m = 90
Answer: 90 grams are needed.
P = m*v
p = momentum
m = mass
v = velocity
p = (37 kg + 18 kg)*(1.2 m/s)
p = (55 kg)*(1.2 m/s)
p = 66 kg-m / s
Answer: A. vegetables, meat, chicken
B. insects, fruits, seeds
Explanation:
A primary consumer is the trophic level in the food chain, which feeds upon the plants and other autotrophs. It includes all the herbivorous animals.
A secondary consumer is the trophic level in the food chain, which feeds upon the herbivorous animals. They are carnivores.
A and B are the two correct options. A will feed upon both plant and animal products such as vegetables and meat, and chicken respectively.
Also B also consumes over the plant products such as fruits and seeds and insects.
