Answer: Your code returns a number of 99.123456789 +0.00455679

Ok, you must see where the error starts to affect your number.

In this case, is in the third decimal.

So you will write 99.123 +- 0.004 da da da.

But you must round your results. In the number you can see that after the 3 comes a 4, so the 3 stays as it is.

in the error, after the 4 comes a 5, so it rounds up.

So the final presentation will be 99.123 +- 0.005

you are discarding all the other decimals because the error "domains" them.

A large aquarium of height 6 m is filled with fresh water to a depth of D = 1.50 m. One wall of the aquarium consists of thick p
Vesnalui [34]

Answer

given,

height of aquarium = 6 m

Depth of fresh water = D = 1.50 m

horizontal length of the aquarium(w) = 8.40 m

total force increased when liquid is filled to depth = 4.30 m

g = 9.81 m/s²

ρ = 998 Kg/m³

force in the aquarium.

dF = PdA

F = \int PdA

F = \int \rho\ g\ y\ (wdy)

F = \rho\ g\ w \int ydy

F = \rho\ g\ w\dfrac{y^2}{2}

F = \dfrac{\rho\ g\ w\ y^2}{2}

At D = 1.5 m

F = \dfrac{980\times 9.8\times 8.4\times 1.5^2}{2}

F = 9.08 x 10⁴ N

At D = 4.30 m

F = \dfrac{980\times 9.8\times 8.4\times 4.3^2}{2}

F = 7.46 x 10⁵ N

Total force on the wall increased by

ΔF  = 74.6 x 10⁴ - 9.08 x 10⁴

ΔF  = 65.52 x 10⁴ N

A battery produces less electrical energy than the total amount of chemical energy contained in its reactive substances. Which s
labwork [276]

Answer:

The energy conversion does not fully occur due to various energy losses.

Explanation:

There are many different types of batteries, but all have three basic components: positive electrode (cathode, or "positive terminal"), negative electrode (anode or "negative terminal"), and electrolyte.

Charging a battery forces ions from  cathode to  anode;  the battery reverses the flow. Over a period of time, this process wears out  cathode, which results in reduced capacity.

Also there can be heat loss inside the system as well which is produced by the conversion from chemical energy.

Hence the chemical energy does not fully convert to electrical energy.

A train starts from rest and accelerates uniformly, until it has traveled 3.7 km and acquired a velocity of 26 m/s. What is the
bogdanovich [222]
We have:
s=3,7km (3700m)
u=0
v=26m/s
a=
t=
We look up for a formula to solve for a:
v²=u²+2as u²=0 so
v²=2as
(26m/s)²=2a3700m
676/7400=a
a=0,09m/s²
