Answer:
n the case of linear motion, the change occurs in the magnitude of the velocity, the direction remaining constant.
In the case of circular motion, the magnitude of the velocity remains constant, the change in its direction occurring.
Explanation:
Velocity is a vector therefore it has magnitude and direction, a change in either of the two is the consequence of an acceleration on the system.
In the case of linear motion, the change occurs in the magnitude of the velocity, the direction remaining constant.
= (v₂-v₁)/Δt
In the case of circular motion, the magnitude of the velocity remains constant, the change in its direction occurring.
= v2/R
In the general case, both the module and the address change
a = Ra ( a_{t}^2 + a_{c}^2)
A) Tolerance
Tolerance is developed after using a drug repeatedly, so the body adapts to it. Because of that, people who develop a tolerance would then need to use more of that drug to get the same effect.
Answer:
All the statements are true
Explanation:
A) Wires are in tension.
It is true because the loads exerted on the bridge are taken by each of the cables of the bridge. these cables transmit the force to the pillars or columns of the bridge. (check the image 01)
B) Large posts are in compression.
It is true each of the loads of the cables is tension, are transmitted to the columns of the bridge, in this way the balance will be maintained (check the image 01)
C) The bridge deck is both in tension and compression.
Yes it is true, the superior part of the deck will be in compression and the inferior part will be in tension, this can be seen in the image 02
Answer:
5.06 m/s
Explanation:
velocity = distance / time
= ( 25.6 - - 14.4) / 7.90 = 5.06 m/s
Answer: radio waves, microwaves, infrared waves.
Explanation:
Electromagnetic spectrum increases in wavelength and decreases with frequency in the following order
Gamma ray, X ray, Ultraviolet rays, Visible light, Infrared rays, Radio waves.
Since 397nm is greater than the value of visible spectrum, this shows that radio waves, microwaves and infrared wave falls in the spectrums of the wavelength value.
