Responda:
400 g
Explicação:
Dado o seguinte:
Deixe Mass (m1) = m em t1 = 45 ° C
Massa (m2) = 200g em t2 = 15 ° C
Equilíbrio térmico (T) = 35 ° C
Usando a relação:
m1 * C * ΔT = m2 * C * ΔT
Onde m1 e m2 são as massas; C = capacidade de calor específico da água e ΔT é a mudança de temperatura
m1 * ΔT = m2 * ΔT
m * (45 ° C - 35 ° C) = 200 * (35 ° C - 15 ° C)
10 * m = 200 * 20
10 * m = 4000
m = 4000/10
m = 400g
Initial speed of Gazelle is along x direction and its value will be
also its initial height is given as
Part a)
now from kinematics along Y direction
as we know that
Part b)
distance moved horizontally
as we know that
now we will have
so it will lend at distance of 4 m.
Part c)
final velocity in vertical direction
so net speed will be

Explanation:
Explanation:
It is given that,
Length of wire, l = 0.53 m
Current, I = 0.2 A
(1.) Approximate formula:
We need to find the magnitude of the magnetic field made by the current at a location 2.0 cm from the wire, r = 2 cm = 0.02 m
The formula for magnetic field at some distance from the wire is given by :
B = 0.000002 T
(2) Exact formula:
B = 0.00000199 T
or
B = 0.000002 T
Hence, this is the required solution.
