Answer:
range = 276.8 km, time = 142 s
Explanation:
The answer would be “the study of matter and energy and how they interact”. :))
A change of colour, heat being released or fizzing (a gas being released)
Answer:
the magnitude and direction of the uniform electric field is 1846.38 N/C and UPWARD respectively
Explanation:
Given the data in the question;
mass m = 1.30 g = 1.30 × 10⁻³ kg
Charge q = +6.90 µC = 6.90 × 10⁻⁶ C
we know that; g = 9.8 m/s
assuming gravity and the electrostatic force are the only forces exerted on the particle, hence the relation is;
F = mg and F = Eq
so
mg = Eq
make E subject of formula
E = mg / q
so we substitute
E = [ (1.30 × 10⁻³) × 9.8 ] / 6.90 × 10⁻⁶
E = 0.01274 / 6.90 × 10⁻⁶
E = 1846.38 N/C
Since the charge is positive ( + ), { direction is Upward }
Therefore, the magnitude and direction of the uniform electric field is 1846.38 N/C and UPWARD respectively
Answers:
a) 0.144 Hz
b) 0.904 rad/s
c) 11.818 m
d)
Explanation:
The rest of the question is written below:
a) Calculate the frequency of oscillation (in Hertz) of the chandelier
b) Calculate the angular frequency 
of the chandelier in radians/ second
c) Determine the length 
in meters of the chandelier
d) That evening, while hanging out in JJ. Thompson's House O' Blues, you notice that (coincidentally) there is a chandelier identical in every way to the one at the Michelson exhibit except this one swings back and forth 0.01 seconds slower, so the period is 
. Determine the acceleration due to gravity in 
at the club.
a) The frequency 
has an inverse relation with the period 
:
(1)
Where 
(2)
b) The angular frequency is given by:
(3)
(4)
(5)
c) Another expression for the period is:
(6)
Where:
is the length of the pendulum
is the mean acceleration due gravity
Isolating :
(7)
(8)
(9)
d) In this case the period of the pendulum is 
. So, we will use equation (7) with this period and find 
:
(10)
(11)
(12) This is the acceleration due gravity at the place, which is near the mean value of
