Answer:
Option d) can not be determined from the given information
Explanation:
Water is a polar molecule consisting of 2 positive hydrogen atoms and a negative oxygen atom.
When a stream of water is deflected by positively charged object, the water molecules are oriented in such a way that oxygen in water, being negatively charge gets attracted to the charged object and aligns near the object whereas hydrogen aligns on the opposite side overcoming the inter-atomic repulsion.
Similar is the case with hydrogen in case the object is negatively charged.
Therefore, it explains that water is a polar molecule and gets attracted to both positive and negative charges and hence, the sign of the object can not be determined.
Answer:
space = 66.24 [m]
Explanation:
To solve this problem we must remember that the average speed is defined as the relationship between a space traveled over a certain time.
where:
space [m]
Av = average velocity = 3.6 [m/s]
time = 18.4 [s]
![space = 3.6*18.4\\space = 66.24 [m]](https://tex.z-dn.net/?f=space%20%3D%203.6%2A18.4%5C%5Cspace%20%3D%2066.24%20%5Bm%5D)
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that the diver will have zero velocity in vertical direction
so here we can say that
Part b)
as we know that
so we will have
Part c)
Distance covered by diver from the edge of the pool is given as
Answer:
4 containers
Explanation:
Given
Average daily demand, d= 750 units
Average time for waiting during production and materials handling, w = 0.15 days
Processing time per container, t = 0.1 days
Container capacity, c = 50 units
Policy variable, α = 5% = 0.05
Number of containers required for component B is calculated as follows;
Total Production/Container Capacity.
Total Production = d(w + t)(1 + α)
Total Production = 750 * (0.15 + 0.1) * (1 + 0.05)
Total Production = 196.875
Number of containers = 196.875/50
Number of containers = 3.9375
Number of containers = 4 --- approximated
Hi!
1. R-Value - a standardized rating for insulating materials
R value is essentially the measure of the resistance to the conductive flow of heat that is determined by the thickness of a material. Different materials are allocated different R values in accordance with the degree of insulation they offer, such as a window, or a wall. It can be said to be the degree of insulation a layer of material offers, and the greater the R value, the higher the resistance it offers to the flow of heat, meaning better the insulation
2. Thermal Equilibrium - when two materials in contact are at the same temperature
Thermal equilibrium is a state when there is no net flow of thermal energy between two materials that are in contact through a pathway that offers thermal conductivity, or in more simple terms permeable to heat. If the temperature of a system is temporally and spatially consistent, the system is said to be in a thermal equilibrium.
3. Insulation - any material that reduces loss of energy due to heat flow
Insulation is when a material prevents the flow or passage of thermal energy or stops heat flow by some degree from one environment to another. For instance, a blanket offers insulation to the body by impairing the flow of heat from the body to the surrounding air. The greater the insulation, the less would be the flow of heat or thermal energy from one place to another.
4. Thermal Conductivity - a physical property of materials that relates its ability to conduct thermal energy
Thermal conductivity is a property of a material that deals with its ability to conduct heat, or thermal energy. The higher the thermal conductivity of a material, the greater would be the heat transfer within the material. For instance, a metal has a higher thermal conductivity that wood, meaning wood allows a lower transfer of heat through it. This is the reason why most cooking utensils such as spatula have a wooden base, instead of a metallic base.
Hope this helps!
