Answer:
2.12 x 10^-4 N
Explanation:
charge on uranium nucleus, Q = 92 e
charge on proton, q = e
distance, d = 1 x 10^-11 m
The force between the two charged particles is given by
e = 1.6 x 10^-19 C
F = 2.12 x 10^-4 N
Thus, the force between the proton and the nucleus of Uranium is 2.12 x 10^-4 N.
Answer: 4.29 m/s
Explanation:
Given
Depth of the well, s = 8.23 m
Time taken to reach the well, t = 0.93 s
Speed of sound = 343 m/s
To solve this, we would be using one of l the laws of motion.
S = ut + 1/2gt², where
S = depth of the well
u = initial speed of toss
g = acceleration due to gravity
t = time taken to reach the well
We would then have
8.23 = 0.93 u + 1/2 * 9.8 * 0.93²
8.23 = 0.93 u + 4.9 * 0.8649
8.23 = 0.93 u + 4.23801
0.93 u = 8.23 - 4.23801
0.93 u = 3.99199
u = 3.99199 / 0.93
u = 4.29 m/s
Therefore, the initial speed of the coin is 4.29 m/s
Answer:
The image of the bottle should appear larger than the actual bottle.
Explanation:
A concave mirror is a kind of lens that diverges towards the center, creating its focus into a reflected image that is larger in size. This is the reason why concave mirrors are known as divergent mirrors because the way the lens is constructed diverges in the middle.
Answer:
Explanation:
uhm answer is 6x8 +6+4 divded by the race seconds
Answer:
0.0483m or 48.3 mm
Explanation:
Let g = 10m/s2
At 8m, the pile has a potential energy of
P = mgh = 3000*10*8 = 240000 J
This energy is converted to kinetic energy once the pile drops down to the bottom:
Taking gravity into consideration, the net force acting on the pile once it hits the ground is
Therefore the net deceleration is:
We can find out how far it's driven into the ground with the following equation of motion:
where v = 0 is the final velocity, which is 0 because it stops, is the initial velocity when it hits the ground, a is the deceleration, and s is the distance it travels into the ground
or 48.3 mm
