The voltage across a membrane forming a cell wall is 72.7 mV and the membrane is 9.22 nm thick. What is the magnitude of the ele

Blizzard [7]

Answer:

The magnitude of the electric field intensity is $E = 7.89 *10^{6} \ V/m$

Explanation:

From the question we are told that

The voltage is $\epsilon = 72.7 \ mV = 72.7 *10^{-3} V$

The thickness of the membrane is $t = 9.22 \ nm = 9.22 *10^{-9} \ m$

Generally the electric field intensity is mathematically represented as

$E = \frac{\epsilon }{t}$

substituting values

$E = \frac{72.7 *10^{-3} }{9.22 *10^{-9}}$

$E = 7.89 *10^{6} \ V/m$

The number of mushrooms needed by a pizza restaurant is given by the

creativ13 [48]

Answer: 24

Explanation:

Given the following equation:

$g=3n$

Where $g$ is the number of mushrooms in a pizza and $n$ the number of pizzas.

If we know the restaurant will make 8 pizzas ( $n=8$ ), then:

$g=3(8)$

$g=24$ This is the needed number of mushrooms for 8 pizzas

Two identical space probes are orbiting Jupiter. Scientists determine that one of the space probes has a larger gravitational fo

galina1969 [7]

If the probes are identical, then the one that feels a larger gravitational
force is orbiting closer to Jupiter than the other one is.

If they're not identical, then the one with greater mass will feel more
gravitational force than the one with less mass, even if they're both
the same distance from Jupiter. (We know this from the experimental
observation that fatter people weigh more, even on Earth.)

Which FBD would represent a car moving right with a motor force of 250 N, and force of friction of 750N, a weight of 8500N and a

babymother [125]

Answer:

Option C

Explanation:

Given that

Motor force is 250 N

Force of friction is 750 N

Weight is 8500 N

And, the normal force is 8500 N

Now based on the above information

Here length of the rector shows the relative magnitude forward force i.e. 250 N i..e lower than the frictional force i.e. backward and weight i.e. 8500 would be equivalent to the normal force
