The growth of plantesimals from smaller solid particles that collided and stuck together
Answer:
Np=130 turns, Is=220 A
Explanation:
Part A:
Ns=100 turns
Vp= 1.5*104 V = 156 V
Vs= 120 V
As Np/Ns= Vp/Vs
⇒ Np=
⇒Np=
Np= 130 turns (It has two significant figures)
Part B
Is=280 A, Vs=120 V, Vp= 1.5*104 V= 156 V
For ideal transformer
Pin=Pout
Ip*Vp= Is*Vs
⇒Ip=()
⇒Ip=
⇒Ip=215.4 A
to represent it as two significant figures we will write as
⇒Ip=220 A

The wavelength of the wave is 0.40 m.
Frequency <em>f </em>of a wave is defined as the number of waves traveling through a point in one second. Wavelength λ is the distance traveled by the wave in one complete time period. The speed of the wave <em>v</em> is related to frequency and wavelength by the expression,
Therefore,
Substitute 200 m/s for <em>v</em> and 500 Hz for <em>f</em>.
Thus, the wavelength of the wave is 0.40 m
Answer:
it remains the same
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.
Hence, the law of conservation of momentum states that, if left alone, the total momentum of two interacting objects that make up a system remains the same.
This ultimately implies that, if two interacting objects exert forces only on each other, their total momentum will remain the same i.e it is conserved.
