Answer:
By the time Mike left his house at 12:00 noon, Erik had already traveled: 2 x 70 mph =140 miles.
308 - 140 = 168 miles left.
Let the time when they meet =T
70T + 50T =168 miles, solve for T
T =7 / 5 =1.4 hours, or 1 hour and 24 minutes after 12:00 noon.
12 + 1.4 =1 O'clock + 24 minutes, or 24 minutes after 1:00 pm when they will meet.
Answer:
B. Herbicides
Explanation:
Nonnative species are species that are found outside their natural habitat. They are also called foreign species. They are introduced through the activities of man either deliberately or in-deliberately . They can be controlled by chemical, biological and mechanical means.
Mowing, net barriers and inspections are mechanical controls.
Biological control is the deliberate introduction of natural enemies of these nonnative/foreign species.
The use of herbicides is a chemical control of plants that grow where they are not wanted.
The correct answer to what additional measurement the student requires is; D. The student has enough information to make the determination
<h3>Understanding Change in Momentum</h3>
Formula for change in momentum is;
ΔP = m(v - u)
Now, this change in momentum is also equal to impulse which has the formula; Impulse = Force(F) × Time(t)
I = F × t
Thus;
m(v - u) = F × t
Now, we are given;
Force exerted on the object and the time interval. Thus;
ΔP = F × t
Thus, the student has enough information to find the change in momentum
The missing options are;
a. The mass of the object.
b. The final speed of the object MOH 5000
c. The distance fallen by the object
d. The student has enough information to make the determination
