The word that identifies the colour of an object seen under ordinary daylight is local colour.
The natural colour of the object, it is best seen on a matte surface because it is not being reflected and therefore distorted. It is the presentation of features of a particular locality.
Answer:
The correct answer is V√5
Explanation:
Let V be the velocity of the satellite orbiting at radius r.
Let V(5r) be the velocity of the satellite orbiting at radius 5r.
Recall:
Escape velocity is given by:
V = √(2gr)
Where V is the escape velocity
g is the acceleration due to gravity
r is the radius of the earth.
With the above equation, we can obtain the answer to the question as follow:
V = √(2gr)
V(5r) = √(2g5r)
Next, we'll obtained the ratio of V(5r) to V as shown below
V(5r) : V => V(5r)/V
V(5r)/V = √(2g5r) / √(2gr)
V(5r)/V = √5
Cross multiply
V(5r) = V√5
From the above illustration, we can see that when the satellite is moved to 3r, then the expression for the velocity will be V√5
Answer:
Streams need vitality to move material, and levels of vitality change as the waterway moves from source to mouth.
At the point when vitality levels are high, huge rocks and stones can be moved. Vitality levels are generally higher close to a waterway's source, when its course is steep and its valley slender. Vitality levels rise considerably higher in the midst of flood.
At the point when vitality levels are low, just little particles can be moved (assuming any). Vitality levels are most reduced when speed drops as a waterway enters a lake or ocean (at the mouth).
Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to cause a jump to a different value. Signals are composed of infinite possible values. ... Sound signals can vary smoothly in volume and pitchAdvantages to using digital signals, including digital signal processing (DSP) and communication systems, include the following:
Digital signals can convey information with less noise, distortion, and interference.
Digital circuits can be reproduced easily in mass quantities at comparatively low costs.
