Given:
450 grams of water (Tw = 24 C)
Thermal capacity of the beaker = negligible
Q = 0
Tice = 0 C
Tfinal = 8 C
450g * (Tf - Tw) + m_ice * (Tice - Tw) = 0
450g * (8 - 24) + m_ice (0 - 24) = 0
solve for m_ice
Answer:
1.63 A and in clockwise direction
Explanation:
The magnetic field due to the rectangular loop is :

Given : W = 4.20 cm

L = 9.50 cm


Rearranging the above equation, we get


I = 1.63 A
So the magnitude of the current in the rectangular loop is 1.63 A.
And the direction of current is clockwise.
DescriptionEcosystem services are the many and varied benefits to humans gifted by the natural environment and from healthy ecosystems. Such ecosystems include, for example, agroecosystems, forest ecosystems, grassland ecosystems and aquatic ecosystems.
Answer:
Explanation:
For magnetic field in a solenoid , the formula is
B = μ₀ n I
Where n is number of turns per unit length and i is current
Putting the values
B = 4π x 10⁻⁷ x (200 / .25) x 2
= 2.00 x 10⁻³ T
