Answer:
A drop in voltage occurs
Explanation:
When electric current flows through a conduct, there are three basic electrical effects that occur to the conductor;
1. A magnetic field is set up around the conductor,
A magnetic field is formed around a conductor when current flows through it which makes it acts like a magnet. Application is used in electric bells.
2. Heat is generated, and
The heating effect of current is due to the conversion of some of the electrical energy that passes through the conductor, into heat energy. Application of heat effect include electric iron, microwave oven, electric bulb, hair straightener etc.
H = I²Rt
3. A drop in voltage occurs
Voltage drop is as a result of current passing through the impedance offers by the conductor or circuit elements. When current passes through a conductor, the resistance offers opposition to the flow of the electric current according to Ohm's law.
Answer:
Slope = M / s
k = +0.016 / s
Explanation:
Given:
- A first order reaction ---- (missing from question)
- Slope is -0.016
Find:
Units of Slope and value of k
Solution:
- The slope of the concentration time graph is called the rate of reaction. For which the rate of reactions is always expressed as change in concentration of reactants per unit time. Hence,
Slope = Change in concentration / time
Slope = M / s
- The units of k constant depends on the order of reaction. The graph given is of first order. Hence, the sum of moles of reactants and products is the same. Hence, the units of constant k is given by:
k = +0.016 / s
Answer:
A. It does not exhibit projectile motion and follows a straight path down the ramp.
Hello
The weight of the object is W=80 N and points downwards, in the vertical direction. The force F exerted by the forearm is perpendicular to the forearm itself, which is at an angle of
above the horizontal; therefore, the angle between the direction of the force F and the direction of the weight P is also
(but upwards). The component of the force F in the vertical direction is
and
must be equal to the weight of the object to compensate it. Therefore we can write
and from this we can find the intensity of the force F:
Answer:
a) Initial Value Problem
dv/dt = 4 - 0.1v
v(0) = 0
b) solution to the IVP
v(t) = 40(1 - e^(-t/10))
c) Limiting velocity
Vo = 40 ft/s
