I believe it is a physical change because it doesnt have anything to do with chemicals
Answer:
13.478 × 10⁻⁵T
Explanation:
Given that,
magnetic field at r = 3cm
due to the current passing through the centre of the hollow cylinder
magnetic field at r = 3cm
due to the current passing through the centre of the hollow cylinder
I₂ = current through the hollow cylinder within r₁ = 1.50cm to r₂ = 3.00cm
so,
So , magnetic of netfield is
= B₂ - B₁
= 13.478 × 10⁻⁵T
Answer:
The power output of the oscillator is 0.350 watt.
Explanation:
Given that,
Diameter = 1.0 mm
Tension = 5.7 N
Frequency = 57.0 Hz
Amplitude = 0.54 cm
We need to calculate the power output of the oscillator
Using formula of the power
Put the value into the formula
Hence, The power output of the oscillator is 0.350 watt.
Answer:
a) m = 59.63 [kg]
b) Wm = 95.41 [N]
Explanation:
El peso de un cuerpo se define como el producto de la masa por la aceleración gravitacional. DE esta manera tenemos:
W = m*g
Donde:
m = masa [kg]
g = gravedad = 9.81 [m/s^2]
m = W / g
m = 585 / 9.81
m = 59.63 [kg]
Es importante aclarar que la masa se conserva independientemente de la ubicación del cuerpo en el espacio.
Por ende su masa sera la misma en la luna.
El peso en la luna se calcula como Wm y es igual a:
Wm = 59.63 * 1.6 = 95.41 [N]
