because they are too small to get shocked

Because the electrical current needs to flow through the ground to finish its course. But birds are not touching the ground so yea.

I hope this helps

What is the current in a circuit if 3.50 C of charge passes any given point in a circuit in 1.80 s?

stepan [7]

Answer:

I = 1.944 A

Explanation:

<u>Given the following data;</u>

Charge, Q = 3.5C

Time, t = 1.8 secs

Charge of a substance is given by the formula;

$Q = It$

Where;

Q is the amount of charge measured in Colombs.

I is the current measured in Amperes.

t is the time measured in seconds.

Making I the subject of formula, we have

$I = \frac {Q}{t}$

$I = \frac {3.5}{1.8}$

I = 1.944 A

Therefore, the current in the circuit is 1.944 Amperes.

PLEASE ANSWER FAST!! A scientist put red blood cells in water that contained salt. Over time, the red blood cells burst. What is

Nitella [24]

It is most likely true that there was a lower concentration of salt in the water than in the cells because when blood cells are put in a hypotonic solution such as pure water, the little to no salt concentration in the water causes the cells to swell and burst. This would occur because the water would try to dilute the solution inside of the blood cell and which would, therefore, cause it to burst. Hope this helps!

A snail moves 18 millimeters every 24 seconds what is the snails rate of speed

Nataly_w [17]

The speed of the snail is given by:

$v=\frac{S}{t}$

where S is the distance covered by the snail and t the time taken.

The snail in the problem moves by S=18 mm in t=24 s, therefore its speed is

$v=\frac{S}{t}=\frac{18 mm}{24 s}=0.75 mm/s$

Please help ASAP will mark brainliest How do we find the amount of uncertainty we should expect in our measurement of the period

kicyunya [14]

Answer:

The relative uncertainty gives the uncertainty as a percentage of the original value. Work this out with: Relative uncertainty = (absolute uncertainty ÷ best estimate) × 100%. So in the example above: Relative uncertainty = (0.2 cm ÷ 3.4 cm) × 100% = 5.9%. The value can therefore be quoted as 3.4 cm ± 5.9%.

Solve for the indicated variable<br> mass (m):<br> 200 N = m (3.5 %)

goblinko [34]

Answer:

5714.29

Explanation:

The given expression is:

200 = m(3.5% )

To solve this problem, we use the concept of multiplicative inverse;

The multiplicative inverse involves using the reciprocal of 3.5% to multiply both side of the expression;

200 = m x $\frac{3.5}{100}$

m = $\frac{100}{3.5}$ x 200 = 5714.29
