A. Females have lower levels of testosterone than males.
It's the only logical answer, all the other ones can happen to both male and female equally
Answer:
His conclusion best illustrates a pessimistic outlook.
Explanation:
As seen in the question above, Ken got 20% of his final grade in the first test he did for this class, that is, there will be other tests that can provide him to reach the grade needed to pass the class. However, even if there are possibilities, he believes that he will not pass the class, he does not have a positive and optimistic view of his future in this class and is sure that he will fail. This negative view of the future is an example of a pessimistic outlook.
1A)
x=v0x*t=v0cosθ*t
x=52co31*3.2=142.6 m
1B)
y0=1/2gt^2-v0y*t=1/2gt^2-v0sinθt
y=0.5*9.8*3.2^2-52*sin31*3,2=23.4 m
2A)
x=2v0^2sin(2θ)/g
v0=[xg/2sin(2θ)]^1/2=14.4 m/s
the initial speed relative to the ground is
v=v0-4.4=10 m/s
2B)
fly time is
t=2voy/g
t=2*14.4/9.8=2.94
2C)
mgy=1/2mv0y^2
y=v0y^2/(2g)=10.58 m
Answer:
1) No, the car does not travel at constant speed.
2) V = 9 ft/s
3) No, the car does not travel at constant speed.
4) V = 5.9 ft/s
Explanation:
In order to know if the car is traveling at constant speed we need to derive the given formula. That way we get speed as a function of time:
V(t) = 2*t + 2 Since the speed depends on time, the speed is not constant at any time.
For the average speed we evaluate the formula for t=2 and t=5:
d(2) = 8 ft and d(5) = 35 ft
Again, for the average speed we evaluate the formula for t=1.8 and t=2.1:
d(1.8) = 6.84 ft and d(2.1) = 8.61 ft
The third one is your answer
