Answer:
(2) −1 e
Explanation:
A quark is the lightest elementary particles which form hadron such as proton and neutron. A quark has fractional charge.
Up, charm and top quarks have
charge where as down, strange and bottom quarks have
charge.
The antiparticle of up quark is antiup quark and has charge
charge.
The antiparticle of down quark is antidown quark and has charge
charge.
An antibaryon is composed of two anti-up quark and one anti-down quark.
Net charge of the anti-baryon is:
Thus, antibaryon has -1e charge.
Answer:
Like all mammals (including whales and dolphins) narwhals need oxygen. ... Fish use their gills to extract oxygen from the water. But narwhals, like us, use their lungs to breathe.

Answer with Explanation:
We are given that
Diameter of coil=d=0.115mm
Radius, r=
Using 
Electric field=E=0.235V/m
T=55 degree C



(a).We know that

Substitute the values


(b).Current density,
Using the formula

c.Total current,I=JA
Where 

Using the formula

I=0.076A
d.Length of wire=l=2m

Substitute the values

I would say B. A stable home and varied activities
