Answer:
Divergent plate margins
Explanation:
Divergent plate margins are constructive zones on the surface of the earth. They are constructive in the sense that new materials are brought to the surface from within the crust.
An example of such is the mid-altlantic ridge. Here as two plates pull apart, new melts up-wells and finds a way to get to the surface where they cool and solidify.
Answer:
greater than 0.10
Explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the statistic, is the mean, is the standard deviation and n is the size of the sample.
We have that:
We are testing if X is greater than 0.45, so our pvalue is 1 subtracted by the pvalue of z = t = 0.45.
z = 0.45 has a pvalue of 0.6736
1 - 0.6735 = 0.3264
So our pvalue is 0.3264, which is greater than 0.10.
So the correct answer is:
greater than 0.10
D = vt
v = 65 km/hr
t = 180 min = 3 hrs
d = (65 km/hr)(3 hrs) = 195 km
The car was going North, so the final complete answer is 195 km North, which is choice (3).
Answer :
(a). The speed of the block is 0.395 m/s.
(b). No
Explanation :
Given that,
Diameter = 20.0 cm
Power = 26.0 MW
Mass = 110 kg
diameter = 20.0 cm
Distance = 100 m
We need to calculate the pressure due to laser
Using formula of pressure
We need to calculate the force
Using formula of force
Put the value into the formula
We need to calculate the acceleration
Using formula of force
Put the value into the formula
(a). We need to calculate speed of the block
Using equation of motion
Put the value into the formula
(b). No because the velocity is very less.
Hence, (a). The speed of the block is 0.395 m/s.
(b). No
