We have:
Initial velocity (u) = 1.6 m/s
Constant acceleration (a) = 0.33 m/s²
Time (t) = 3.6 sec
There are five constant acceleration equations that would help us to find the velocity:





Since we have

and we want

We will use the first formula



m/s
Answer:
joules
joules
Explanation:
Let us convert the time in hours into seconds

Change in internal energy

where E is the internal energy in Joules
p is the power in watts
and t is the time in seconds

Joules
Amount of work done by the system

where P is the pressure and V is the volume
Substituting the given values in above equation, we get -

liter-atmospheres
Work done in Joules

Joules

Substituting the given values we get -

Thus
joules
joules
Rutherford's experiment<span> utilized positively charged alpha particles (He with a +2 charge) which were deflected by the dense inner mass (nucleus). The conclusion that could be formed from this result was that </span>atoms<span> had an inner core which contained most of the mass of an </span>atom<span> and was positively charged.</span>
Answer:
a) 19440 km/h²
b) 10 sec
Explanation:
v₀ = initial velocity of the car = 45 km/h
v = final velocity achieved by the car = 99 km/h
d = distance traveled by the car while accelerating = 0.2 km
a = acceleration of the car
Using the kinematics equation
v² = v₀² + 2 a d
99² = 45² + 2 a (0.2)
a = 19440 km/h²
b)
t = time required to reach the final velocity
Using the kinematics equation
v = v₀ + a t
99 = 45 + (19440) t
t = 0.00278 h
t = 0.00278 x 3600 sec
t = 10 sec
