The displacement of Curiosity is 2.334 m
The given parameter:
maximum speed of Curiosity, v = 0.14 km/hr
time of motion of Curiosity = 60 s
To find:
- the displacement of Curiosity
The displacement of Curiosity is calculated as follows;
- convert the speed in km/hr to m/s by dividing by 3.6 km/hr
- 0.14 km/hr = 0.0389 m/s
The displacement of Curiosity = speed x time
The displacement of Curiosity = 0.0389 m/s x 60 s
The displacement of Curiosity = 2.334 m
Thus, the displacement of Curiosity is 2.334 m

Answer:
can a fire have a shadow?
Yes it can actually.
edit:Fires can have shadows because they contain hot air and soot, and not because they contain light.
Answer:
B
Explanation:
Friction acts in a direction opposite to the motion of an object
Answer:
Q = 1.35*10⁻¹¹ C.
Explanation:
By definition, the capacitance of a capacitor, is the charge on one of the plates, divided by the potential difference between them, as follows:
At the same time, we can show (applying Gauss' Law to the surface of one of the plates), that the capacitance of a parallel-plate capacitor (with a dielectric of air), can be written as follows:
C = ε₀*A / d
Replacing by the values of A, and d, and taking into account that
ε₀ = 8.85*10⁻¹² F/m,
we get the value of the capacitance as follows:
C = 8.97*10⁻¹² F
As the voltage of an AA battery is 1.5 V, and is all applied to the capacitor, we can conclude that the charge on one of the plates is as follows:
Q = C* V = 8.97*10⁻¹² F* 1.5 V = 1.35*10⁻¹¹ C
Answer:
1/4 of the original
Explanation:
That would be TWO half lives:
1/2 * 1/2 = 1/4 <======= 1/4 would be left
