Answer:
B
Explanation:
Because it has to do with the darker the object the better it emitts heat.
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"What element has conductivity,shiney luster,magnetic
-science"
silicon has a shiny luster,But it is brittle and conducts electricity poorly.Some metalloids change their characteristics when they react with different elements.Luster conductivity and malleability are physical properties can be observed be observed without attempting to change the identity of the substance.The term physical property is an observable characteristics of a substance. in this case the luster conductivity and malleability of metals are the properties, which can be observed by our senses.It differs from chemical properties which can only be observed when the substance change its chemical identity.
Metal are solid at room temperature with the exception of mercury which is liquid at room temperature.Luster metal have the quality of reflection light from its surface and can be polished e.g gold,silver and copper.
Answer:
Explanation:
In addition to the 'daughter' products, two or three neutrons also explode out of the fission reaction and these can then collide with other uranium nuclei which are unstable so these cause further fission reactions. This is known as a chain reaction .

The magnetic dipole moment of the current loop is 0.025 Am².
The magnetic torque on the loop is 2.5 x 10⁻⁴ Nm.
<h3>What is magnetic dipole moment?</h3>
The magnetic dipole moment of an object, is the measure of the object's tendency to align with a magnetic field.
Mathematically, magnetic dipole moment is given as;
μ = NIA
where;
- N is number of turns of the loop
- A is the area of the loop
- I is the current flowing in the loop
μ = (1) x (25 A) x (0.001 m²)
μ = 0.025 Am²
The magnetic torque on the loop is calculated as follows;
τ = μB
where;
- B is magnetic field strength
B = √(0.002² + 0.006² + 0.008²)
B = 0.01 T
τ = μB
τ = 0.025 Am² x 0.01 T
τ = 2.5 x 10⁻⁴ Nm
Thus, the magnetic dipole moment of the current loop is determined from the current and area of the loop while the magnetic torque on the loop is determined from the magnetic dipole moment.

Much energy as would Microraptor gui have to expend to fly with a speed of 10 m/s for 1.0 minutes is 486 J.
The first step is to find the energy that Microraptor must release to fly at 10 m/s for 1.0 minutes. The energy that Microraptor must expend to fly can be found using the relationship between Power and Energy.
P = E/t
Where:
P = power (W)
T = time (s)
Now, a minimum of 8.1 W is required to fly at 10 m/s. So, the energy expended in 1 minute (60 seconds) is
P = E/t
E = P x t
E = 8.1 x 60
E = 486 Joules
Thus, the energy that Microraptor must expend to fly at 10 m/s for 1.0 minutes is the 486 J.
