Answer:
Ernest Rutherford observed that particles with a positive charge deflected when passing through a thin sheet of gold foil, concluding that the atom's positive part is small and dense.
Explanation:
The Ernest Rutherford experiment describes planetary model of an atom. According to the model, an atom has a tiny, compact, positively charged centre called a nucleus, where almost all of the mass is concentrated, while light, negatively charged particles called electrons orbit far around it, much like planets orbit the Sun. In his experiment, the observation that a positive charge is deflected through a thin sheet of gold foil led to the conclusion that the deflection some of the positive charge occurs in a small region of the atom. At the same time, the majority passed through the atom (which was also concluded to be empty space).

Answer:
Explanation:
mass, m = 50 g
moment of inertia, I = 9 x 106-5 kg m^2
radius, r = 0.7 cm
(a) As it moving downwards
Let T be the tension in the string
T = m (g + a) .... (1)
where, a be the acceleration
τ = I α = T r
α = a / r
So, I x a / r = T x r
a = T r^2 / I
Substitute in equation (1) we get
a = m (g + a) r^2 / I
a = mgr^2 / (I - mr^2)
a = 0.050 x 9.8 x 0.007 x 0.007 / (9 x 10^-5 - 0.050 x 0.007 x 0.007)
a = 2.401 x 10^-5 / (87.55 x 10^-6)
a = 0.274 m/s^2
τ = I x α = I x a / r
τ = 9 x 10^-5 x 0.274 / 0.007
τ = 3.52 x 10^-3 Nm
(b) α = a / r
α = 0.274 / 0.007 = 39.14 rad/s^2
Answer:
attracted
Explanation:
Electrons are negative.
A positively charged object will attract a negatively charged object
Explanation :
It is given that :
The initial velocity of the car is 10 m/s.
Juliette sets the acceleration to zero.
We know that, acceleration \
where,
u is the initial velocity and v is the final velocity.
So, final velocity will become 10 m/s.
Hence, the car will move with the constant velocity i.e. 10 m/s.
So, Shakina described that the car will move with the constant velocity of 10 m/s as acceleration is zero.
