The
horizontal component of an angular distance can be calculated by multiplying the
distance with the cosine of the angle, Dx = D * cos θ
While
the vertical component is calculated by multiplying the distance with the sine
of the angle, Dy = D * sin θ
The
resultant displacement can then be obtained using the formula for hypotenuse
and summations of each component:
R^2
= (summation of Dx)^2 + (summation of Dy)^2
summation
of Dx = 600 * cos47 + 500 * cos128 + 300 * cos209 + 400 *
cos(-77) = -71.0372
summation of Dy = 600 * sin47
+ 500 * sin128 + 300 * sin209 + 400 * sin(-77) = 297.6267
<span> Note: you have to draw the lines to correctly
determine the angles</span>
R^2 = (-71.0372)^2 + 297.6267^2
R = 306 m
The resultant angle is:
tan θ = Dy / Dx
θ =
tan^-1 (297.6267 / -71.0372)
θ =
103˚ = [N 13˚ W]
Therefore
displacement is 306 m <span>[N 13˚ W].</span>
It still has a definite temperature.
Answer:
5.9 m
Explanation:
v=6m/s
H=5m
h=0.17m
g=10 m/s
First we find the time in which ball reaches the entrance of coffee can. For this purpose the ball has to travel a distance S vertically downward such that
S= 5-0.17 = 4.83 m
While falling down Vi =0
g= 10 m/sec2
t = ?
S=vit+1/2 gt2
==> 4.83=0+0.5×10×
==> 4.83=5×
==> =4.83/5 = 0.97
==> t= 0.98 sec
So in this time the ball reaches the coffee can height level. Now let's calculate horizontal distance covered by the ball in this time.
Horizontal distance = horizantal velocity × time
= 6 × 0.98 = 5.9 m
Answer:
We can conclude by saying that in the beginning current will increase but after sometime, it becomes saturated.
Explanation:
Note: No information on change in number of electron generated.
Since there is a collision, the electrons emitted will not reach the collector at same time. As the voltage is increased, the the speed with which the electrons will reach the collector starts to increase. Due to this, electric current will first increases till all the emitted electrons reach the collector. Since we are not provided with the information that number of electrons generated are changing, after increasing voltage current will increase for some time and then reaches a saturated state.
We can conclude by saying that in the beginning current will increase but after sometime it becomes saturated.
Answer:
Oxidative phosphorylation
Explanation:
This takes place mostly in the organelle called the mitochondrion.
Oxidation of nutrients in cells by enzymes results in the release of the chemical energy present in the molecular energy.
The NADH and succinate products of the citric acid cycle are also oxidized. All this series of reactions takes place in the Electron transport system.The energy from the oxidation is used to produce adenosine triphosphate (ATP) hence the name oxidative phosphorylation.
