Why are all the different parts of the cell necessary?<br> Answer

victus00 [196]

Answer:

Every individual part of a cell has a very important and specific purpose. If even one of these went wrong it would throw off the other parts and most likely damage the cell. They all work in a bit of unison, so it's very important nothing bad happens to one. Hope this helps you out! :)

One of the dangers of tornados and hurricanes is the rapid drop in air pressurethat is associated with such storms. Assume that

Oksi-84 [34.3K]

Answer:

The net outward force is exerted on a square window of the house is $4.5930\times10^{4}\ N$ .

Explanation:

Given that,

Pressure = 1.02 atm

External air pressure = 0.910 atm

Distance = 2.03 m

We need to calculate the net outward force

Using formula of force

$F= PA$

Where, P = pressure

F = force

A = area

Put the value into the formula

$F=(1.02-0.910)\times101325\times(2.03)^2$

$F=4.5930\times10^{4}\ N$

Hence, The net outward force is exerted on a square window of the house is $4.5930\times10^{4}\ N$ .

Calculate the KE of a 3.1 kg toy cart that moves at 4.8 m/s. Calculate the KE of the same cart at twice the speed.

lisov135 [29]

When v= 4.8 m/s:

E.K=mv²/2
=3,1(4.8)²/2
=35.712J

when v= 2(4.8):

E.K=mv²/2
=3.1(9.6)²/2
=142.848J

Substance A has a higher heat capacity than does substance B, and substance B has a higher heat capacity than does substance C.

svetlana [45]

A < B < C

C will increase faster than B which is faster than A

A coil of wire with 50 turns lies in the plane of the page and has an initial area of 0.250 m2. The coil is now stretched to hav

Oxana [17]

Answer:

The induced emf in the coil is 170 volt and its direction is clockwise direction.

Explanation:

Given that,

Number of turns of a coil, N = 50

Initial area, $A_i=0.25\ m^2$

Final area, $A_f=0$

Time, t = 0.1 s

The magnetic field points into the page and has a strength of 1.36 T.

We need to find the magnitude and direction of the average value of the induced emf. Due to change in area of the coil and emf will be induced in it. The induced emf is given by :

$\epsilon=-N\dfrac{d\phi}{dt}\\\\\text{since}\ \phi=BA\\\\\epsilon=-N\dfrac{d(BA)}{dt}\\\\\epsilon=-NB\dfrac{A_f-A_i}{dt}\\\\\epsilon=-50\times 1.36\dfrac{0-0.25}{0.1}\\\\\epsilon=170\ V$

So, the induced emf in the coil is 170 volt and its direction is clockwise direction. Hence, this is the required solution.
