Answer:
<em>The bicyclist goes at 5 m/s</em>
Explanation:
<u>Motion With Constant Acceleration
</u>
It's a type of motion in which the velocity of an object changes uniformly in time.
The equation that rules the change of velocities is:
Where:
a = acceleration
vo = initial speed
vf = final speed
t = time
It's given a bicyclist is traveling at v0=+25 m/s and decelerates at . We are required to calculate the speed after t=5 seconds.
Applying the formula:
The bicyclist goes at 5 m/s
<span>Diamond slowdown light more than Quartz , because diamonds have a greater index of refraction. Light will bend when its move from one medium to another. The Index of Refraction of Material is found by comparing the speed of light in their respective mediums.</span>
The formula for centripetal acceleration is v^2/r, where v is the tangential velocity, and r is the radius.
<span>Alternatively, w^2r where w is the angular velocity and r is the radius.
</span><span>The centripetal acceleration is ar=(((1.70 rev/s)*(2*pi rad/rev))^2)*(0.132m)= 15.06 m/s^2 </span>
It's not. It's equivalent to the transfer of that many elementary charges <u>every second</u> .
The elementary charge (charge on an electron) is
1.60 x 10⁻¹⁹ coulomb / electron.
The number of electrons in a Coulomb is the reciprocal of that number.
6.25 x 10⁻¹⁸ electrons / Coulomb.
There's the number. 1 Coulomb <em>per second</em> is called 1 Ampere.
Answer:
Friction
Explanation: is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static friction acts on objects when they are resting on a surface.Nov 3, 2021
