This question is a bit ambiguous because all parts of a scientific argument must be supported by valid data. However, among the choices, the closest synonym to "valid data" would be evidence. Evidence is the body of facts or information that support a given idea.
Answer:
0.765m
Explanation:
gravitational potential energy GPE = mass * acceleration due to gravity * height
Given
GPE = 30Joules
Mass m = 4kg
acceleration = 9.8m/s²
Required
Height h
From the formula
h = GPE/mg
h = 30/4(9.8)
h = 30/39.2
h = 0.765m\
Hence the height of the counter is 0.765m
Answer:
(a) Acceleration of electron= 5.993×10²⁰ m/s²
(b) Acceleration of proton= 3.264×10¹⁷ m/s²
Explanation:
Given Data
distance r= 6.50×10⁻¹⁰ m
Mass of electron Me=9.109×10⁻³¹ kg
Mass of proton Mp=1.673×10⁻²⁷ kg
Charge of electron qe= -e = -1.602×10⁻¹⁹C
Charge of electron qp= e = 1.602×10⁻¹⁹C
To find
(a) Acceleration of electron
(b) Acceleration of proton
Solution
Since the charges are opposite the Coulomb Force is attractive
So
From Newtons Second Law of motion
F=ma
a=F/m
For (a) Acceleration of electron
For(b) Acceleration of proton

(0.15 x g)/100 = 0.0147N. per cm. length.
<span>Torque short end = (0.0147 x 9) = 0.1323N/cm. </span>
<span>Torque long end = ((100 - 18)/2) x 0.0147 = 0.6027N/cm. </span>
<span>Difference = (0.6027 - 0.1323) = 0.4704N/cm. </span>
<span>(0.4704/3.2) = 0.147cm. from the 18cm. mark, = 17.853cm. from the 0 end of the stick.</span>
