Answer:
-1.11 m/s²
Explanation:
v = at + v₀
Given v = 20 m/s, v₀ = 120 m/s, and t = 1.5 min = 90 s:
20 m/s = a (90 s) + 120 m/s
a = -1.11 m/s²
Answer:
The answer would be A.)Early signs of cardiovascular disease and sleep apnea.
Explanation:
I got it right on the hope test.
Answer:
i)The ball shot out of the smokestack of a train moving in a straight line at constant speed will fall back into the smokestack
ii)The ball shot out of the smokestack of a train moving in a straight track ( gaining speed ) will fall behind the smoke stack
iii) The ball shot out of the smokestack of a train moving in a circular track at constant speed will fall away from the smokestack in a direction that is away from the middle of the circular track
Explanation:
The ball shot out of the smokestack of a train moving in a straight line at constant speed will fall back into the smokestack
The ball shot out of the smokestack of a train moving in a straight track ( gaining speed ) will fall behind the smoke stack
The ball shot out of the smokestack of a train moving in a circular track at constant speed will fall away from the smokestack in a direction that is away from the middle of the circular track
C. 1 Joule
Explanation:
Given:
Voltage = 1V
Quantity of charge = 1coulomb
Unknown:
Energy = ?
Solution:
The amount of work done is often related to the energy in a system.
In this electrical circuit, work done is the voltage that moves a particular charge.
work done = q x v
q is the quantity of charge
v is the voltage
the potential difference in circuit is the driving force of charges.
Work done = energy = qv
inputting the parameters;
Work done = 1 x 1 = 1J

Answer:
60°
Explanation:
I₀ = Intensity of unpolarized light
θ = Angle between the axis of the filter and polarization direction
Intensity of polarzied light
Here, the light that is transmitted is reduced by 25% that means
So,
∴ The angle between the axes of the polarizer and the analyzer is 60°
