ANSWER:
The easiest way to get a fairly accurate measure of your water flow rate is to time yourself filling up a bucket. So for example if you fill up a 10 litre bucket in 1.5 minutes, then your flow rate will be: 10/1.5 = 6.66 Litres per minute.
Answer:
1176 N
Explanation:
We are given that
Mass of car=1280 kg
Mass of trailer==350 kg
Car exerts a horizontal force against the ground =N
Coefficient of friction=
We have to find the force exerted by car on the trailer.
Substitute the values then we get
Force exert on the trailer
Hence, the car exerts force on the trailer=1176 N
Answer:
f(-9) = 184
Explanation:
f(x)=3x²+5x-14
f(-9)= 3(-9)² +5(-9)-14 Order of Operations : Exponents
= 3(81)+5(-9)-14
= 243+5(-9)-14
= 243-45-14
= 198-14
f(-9)= 184
Hope this helps :)
Answer:
1039.23 m/s
Explanation:
Given:
Height, H = 3 x 10⁵m
acceleration of gravity on lo, a = 1.80 m/s² toward moon's surface i.e -1.80m/s² with respect to the earth
Now, at its highest point the velocity i.e the final velocity 'v' = 0m/s.
Now using the Newton's equation of motion
v² - u² =2as
where,
v = final velocity
u = initial velocity
a = acceleration
s = distance
now,
substituting the values we get
0²-u² = 2 × (-1.80) × 3 x 10⁵
or
Hence, the <u>initial velocity</u><u> with which the material is ejected is </u><u>1039.23 m/s</u>
