Answer would be: alternating.There is no electrical connection between the two coils. These only work if alternating current is supplied to the main coil. If DC was supplied, there would be no flow of current in the minor coil.
<span>To answer this problem, we use balancing of forces: x and y components to determine the tension of the rope.
First, the vertical component of tension (Tsin theta) is equal to the weight of the object.
T * sin θ = mg =</span> 1.55 * 9.81 <span>
T * sin θ = 15.2055
Second, the horizontal component of tension (t cos theta) is equal to the force of the wind.
T * cos θ = 13.3
Tan θ = sin </span>θ / cos θ = 15.2055/13.3 = 1.143
we can find θ that is equal to 48.82.
T then is equal to 20.20 N
Answer:
Properties of minerals are:
B) made of just one substance
C) made of at least two substances
Explanation:
Minerals & their Properties
Minerals are defined as the naturally occurring, solid inorganic chemical compounds. They have an orderly internal structure with definite chemical composition.
Fossils usually contain single or multiple minerals such as Calcite, Quartz, Phosphate etc. Sometimes minerals are visible in the crystalline form in fossils. So, we cannot say that minerals are made of fossils. Instead, fossils can be made of minerals.
According to the prime and standard definition given by scientists, minerals are usually composed of chemical compounds or multiple compounds such a Halite which composed of Sodium and Chlorine elements. But they can be made of just one substance or element.
Now talking about the tiny grains of sand, that are made of minerals. So, instead of saying that minerals are composed of tiny grains of sand, we should say that sand is made of minerals. The most common mineral which forms sand is Quartz. Sand has a versatile mixture of substances besides minerals.
Newton’s second law states that force is the product of
mass and acceleration. This is expressed mathematically as:
F = m * a
Where F = force, m = mass, a = acceleration
Since in the given problem, the force is constant or same
force is acting upon two objects. Therefore we can simply equate the expression
m * a of the 2 objects.
m1 * a1 = m2 * a2
Where m1 = 2 kg, a1 = 38 m/s^2, m2 = 19 kg. Therefore
finding for a2:
2 kg * 38 m/s^2 = 19 kg * a2
<span>a2 = 4 m/s^2 (ANSWER)</span>
The company's method used in its marketing strategy as what is described in the description would be reverse logistics. In addition, a reverse logistics technique mainly involves re-using the company's products produced for the reason of properly disposing in, and could be used as another resource for future productions.
