$\\ \sf\Rrightarrow F=ma$

Take a to left
As it's multiplied on right side it will be divided on right side.

$\\ \sf\Rrightarrow \dfrac{F}{a}=m$

$\\ \sf\Rrightarrow m=\dfrac{F}{a}$

Anika [276]

Answer:

Incomplete questions

Let assume we are asked to find

Calculate the induced emf in the coil at any time, let say t=2

And induced current

Explanation:

Flux is given as

Φ=NAB

Where

N is number of turn, N=1

A=area=πr²

Since r=2cm=0.02

A=π(0.02)²=0.001257m²

B=magnetic field

B(t)=Bo•e−t/τ,

Where Bo=3T

τ=0.5s

B(t)=3e(−t/0.5)

B(t)=3exp(-2t)

Therefore

Φ=NAB

Φ=0.001257×3•exp(-2t)

Φ=0.00377exp(-2t)

Now,

Induce emf is given as

E= - dΦ/dt

E= - 0.00377×-2 exp(-2t)

E=0.00754exp(-2t)

At t=2

E=0.00754exp(-4)

E=0.000138V

E=0.138mV

b. Induce current

From ohms laws

V=iR

Given that R=0.6Ω

i=V/R

i=0.000138/0.6

i=0.00023A

i=0.23mA

What are two things that happen to the sugars that are made by the plant during photosynthesis?

Elena-2011 [213]

Answer:

The sugars produced by photosynthesis can be stored, transported throughout the tree, and converted into energy which is used to power all cellular processes. Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

Explanation:

I think this is correct lol.

lightning sometimes happens between clouds. suggest a possible way that a discharge can occur between clouds

nataly862011 [7]

Most lightning happens inside a cloud, but sometimes it happens between the cloud and the ground. A build up of positive charge builds up on the ground beneath the cloud, attracted to the negative charge in the bottom of the cloud. The ground's positive charge concentrates around anything that sticks up-trees, lightning conductors, even people. The positive charge from the ground connects with the negative charge from the clouds and a spark of lightning strikes.

Evaluate the efficiency of two identical-looking conveyor belts. Belt A can move a 10 newtons weight one meter in 3 seconds. Bel

LUCKY_DIMON [66]

The Belt A has an efficiency of 50% while the Belt B has an efficiency of 25%

Why?

To calculate the efficiency of the belts, we need to consider that both conveyor belts are identical looking and both weights are equal (10 Newtons).

We need to remember that the formula to calculate work is equal to:

$Work=Force*distance(Joule)$

Also,

$Joules=\frac{Newton}{m}$

We know the following:

For belt A,

$weight=10N\\time=3seconds\\distance=1meter\\Joule=\frac{N}{m}=\frac{10N}{1m}=10J$

For belt B,

$weight=10N\\time=3seconds\\distance=2meter\\Joule=\frac{N}{m}=\frac{10N}{2m}=5J$

Now, to calculate the efficiencty of the belts, we can use the following formula:

$Efficiency=\frac{Work(Out)}{Work(Starting)}*100$

We know that for both belts, the starting work was 20 J.

So, calculating we have:

$Efficiency_{BeltA}=\frac{10J}{20J}*100=50(percent)$

$Efficiency_{BeltB}=\frac{5J}{20J}*100=25(percent)$

Hence, we can see that The Belt A has an efficiency of 50% while The Belt B has an efficiency of 25%

Have a nice day!
