Answer:
B
Explanation:
because it has more power
A motion in one dimension is a type of motion that is always along a straight line and has a constant acceleration.
Motion refers to a change in the location (position) of an object or physical body with respect to a reference point, especially due to the action of an external force.
In Science, the motion of an object or physical body is described in terms of the following parameters:
Furthermore, there are three (3) forms of motion based on dimension and these include:
1. Motion in one dimension
2. Motion in two dimension
3. Motion in three dimension
A motion in one dimension (one-dimensional motion) is also referred to as rectilinear or linear motion. Also, it is always along a straight line in any direction and characterized by constant acceleration.

Voltage = joules/coulomb
1 coulomb = 6.25 x 10^18 electrons
8.5 x 10^18 electrons = 1.36 coulombs
136 joules / 1.36 coulombs = 100 volts
===================================
The statement regarding the ball is false. Any object that's not hanging from something
or resting on something is accelerating downward on account of gravity. No matter what
direction you throw the ball, or how hard, its acceleration is 9.8 meters per second^2
directed downward, from the instant it leaves your hand until it hits the ground.
A fertilized cell divides many times to form an embryo. - true
Human reproduction requires two reproductive cells from each parent. - true
Growth is caused by cells in your body dividing and making new cells. - false
A cell nucleus contains DNA, which is a chemical code for all inherited traits. - true
Answer:
Explanation:
The question relates to Doppler effect and beat.
The observer is moving towards the reflected sound so apparent frequency will be increased
f = f₀ x (V + v₁) / (V - v₂)
f is apparent frequency , f₀ is real frequency , V is velocity of sound , v₁ is velocity of observer and v₂ is velocity of source . Here
v₁ = v₂ = vp as both observer and source have same velocity
f = f₀ x (V + v₁) / (V - v₂)
205 +5 = 205 x (344 +vp)/ ( 344 - vp)
1.0234 = (344 +vp)/ ( 344 - vp)
= 352 - 1.0234vp = 340+vp
12 / 2.0234vp
vp = 6 m /s approx.
