The Eastern coastline of South America and West coastline of Africa looked like they fit together
Answer:
Assuming the charged density in the insulated solid sphere of radius 3.1m is 8.8e-9, the electric field at 5.2 meters is 73.1256 .
Explanation:
The electric charge linear density is equal to 8.8 x
the radius of the sphere is 3.1m
The magnitude of the electric field at the radius of the sphere equal to 5.2 meters can be calculated with the formula ;
- E = λ / 4πε₀ [ r / α ( α + r ) ]
Solution:
E = 8.8 x / 4πε₀ [ 3.1/ 5.2( 5.2 + 3.1) ]
= 1018.0995 [0.07183]
= 73.1256
Answer:
B
Explanation:
to see how fast she is going per second, you would have to divide the distance traveled by the seconds it took to travel the distance
Answer:
360 km/h
Explanation:
Velocity =Distance/time ⇒ distance = velocity×time
Distance for 1st 2 h = 400×2 = 800 km
Distance for next 1 h = 300×1 = 300 km
Distance for last 2 h = 350×2 = 700 km
Therefore total distance traveled = 1800 km
So average speed = 1800/5 = 360 km/h
Answer:
The initial velocity of the gymnast is 8.5 m/s.
Explanation:
We can use the kinematic equation
to figure out the initial velocity of the gymnast.
Now, when the gymnast reaches the maximum height, the distance he has traveled is , and his velocity is zero; therefore .
Thus, we have
