Answer:
answer is 11.76 meter
Explanation:
use 2nd equation of motion
S=ut+1/2at^2
As a system is cooled to its freezing point, the kinetic energy of the particles in the system will lower so the movement are much slower. Cooling means taking out heat from the system. This process is a physical change because it is only the phase of the system is changed and it is still the substance after the process.
Answer:
1/5 or .2
Explanation:
you put miles over seconds 3/15 then simplify to 1/5 to get miles per second
Using Ohm's Law:
V = IR
Where V = Voltage in Volts, I = Current in Ampere, R = Resistance in Ohms
V = IR
1.5 = I * 3
1.5 = 3I
3*I = 1.5
I = 1.5/3
I = 0.50 A
Current in the Circuit is 0.50 Ampere.
Answer:
134 kg
Explanation:
The snowmobile is moving at constant speed, so the acceleration is 0.
Sum of the forces in the x direction:
∑F = ma
F − 360 = 0
F = 360
Friction force equals the normal force times the coefficient of friction:
Nμ = 360
On level ground, the normal force equals the combined weight:
(m + 50)g μ = 360
m + 50 = 360 / (gμ)
m = -50 + 360 / (gμ)
m = -50 + 360 / (9.8 × 0.2)
m ≈ 134 kg
Round as needed.
