Answer:
D. 10
Step-by-step explanation:
Since you divided by 2. You want to multiply to go back wards.
35×2=70
They already give you base(b=7) so to find the height you need to divide to go backwards since you multipled bh.
70÷7=10
now plug it in to see if the equation is right.
35= 1÷2 (7×10)
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r
1
mv
2
=
r
2
mu
2
................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v
2
=
2
1
u
2
⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Answer:
1/61.8 its right valu of x
Step-by-step explanation:
here we find the first valu and second is also same but there isx so cross the eqal side and get same answer
Is the question how long would the 185 petri dishes last because if so it would be about 15 days
