Answer:
D
Explanation:
Most electric vehicles can go at least 100.....few, if any, can go 400 or more on a single charge
Answer:
Reynolds number is 293068.43.
Explanation:
Step1
Given:
Water temperature is 98 °F.
Diameter of the pipe is 4 in
Length of the pipe is 870 feet.
Flow rate of water is 260 gallons per minute.
Calculation:
Step2
Water kinematic viscosity at temperature 98 F is ft²/s.
Find the velocity of the water as follows:
Q=AV
V=6.638 ft/s
Step3
Expression for Reynolds number is given as follows:
Here, v is velocity, is kinematic viscosity, d is diameter and Re is Reynolds number.
Substitute the values in the above equation as follows:
Re= 293068.43
Thus, the Reynolds number is 293068.43.
Answer:
500 N
Explanation:
Given;
Mass of the car, M = 1000 kg
initial speed of the car, u = 0 m/s
Final speed of the car, v = 60 m/s
Time, t = 1 min = 60 s
Now,
Force, F is given as:
F = Ma
where,
a is the acceleration
From the Newton's equation of motion, we have
v = u + at
on substituting the values, we get
60 = 0 + a × 60
or
a = 1 m/s²
Thus,
Force = 1000 × 1 = 1000 N
now,
this force will be equal to the friction force provided by the rear wheels
let the friction force on a single rear wheel be 'f'
thus,
2f = 1000 N
or
f = 500 N
Answer:
The answer is one and four.
Explanation:
I had this question on Edgenuity.
Answer:
Explanation:
For ligation process the 1:3 vector to insert ratio is the good to utilize . By considering that we can take 1 ratio of vector and 3 ratio of insert ( consider different insert size ) and take 10 different vials of ligation ( each calculated using different insert size from low to high ) and plot a graph for transformation efficiency and using optimum transformation efficiency we can find out the insert size.
