Answer:
(a) E = 3.065 * 10^21 N/C
(b) The direction is radially outward.
Explanation:
Parameters given:
Number of protons = 94
Charge of proton = 1.6023 * 10^-19 C
Radius of nucleus = 6.65 fm = 6.65 * 10^-15
At the surface of the nucleus, Electric field, E is given as:
E = kq/r^2
Where k = Coulombs constant
r = radius of nucleus
=> E = (9 * 10^9 * 94* 1.6023 * 10^-19)/(6.65 * 10^21)
E = 3.065 * 10^21 N/C
The direction of the field is radially outward.
Answer:
A. 1.3 per season
B. 0.77 per season
Explanation:
In the organisation's website, the National Oceanic and Atmospheric Administration, NOAA, in 2004 stated that, since 1995, there has been an increase (above average) in the Atlantic ocean's tropical clone activity corresponding to the multi-decadal oscillation's active phase
That since 1995 there has been 13 tropical storm and 7.7 hurricanes
Therefore;
Since the number of years between 1995 and 2004 = 10 Years, we have;
A, The average number of tropical storm per, season = 13/10 = 1.3 per season
B. The average number of hurricane, per season = 7.7/10 = 0.77 per season.
Answer:
Explanation:
As we know that total impulse is given as the product of mass and change in velocity
so here we will have
here we will have
also we know that mass of the rocket is
m = 0.192 kg
now we will have
Answer:
The slopes for each of the four line segments are , , and , respectively.
Explanation:
There are four line segments:
(i) Line A: ,
(ii) Line B: ,
(iii) Line C: ,
(iv) Line D: ,
The slope of each line segment represents the acceleration of the particle, which can calculated by the geometrical concept of secant line. Hence, we proceed to determine the acceleration associated with each line segment:
Line A
Line B
Line C
Line D
The slopes for each of the four line segments are , , and , respectively.
The centripetal acceleration of the tip of the fan blade is 96.23 m/s²
<h3>What is centripetal acceleration?</h3>
The acceleration developed when a body is moving in circular way, directed towards the center of the circular path.
The tip of a fan blade is 0.61 m from the center of the fan. the fan turns at a constant speed and completes 2 rotations every 1.0 s
ac = ω²r
where ω = angular speed = 2πN/60, N = Rotation per minute
From the question, N = 2 x 60/1 = 120 RPM
So, the angular speed will be
ω = 2π x 120 /60
ω = 12.56 rad/s
Then, the centripetal acceleration is
ac = (12.56)² x 0.61 m
ac = 96.23 m/s²
Thus, centripetal acceleration of the tip of the fan blade is 96.23 m/s²
