Answer:
x = 5.29 m
Explanation:
given,
weight of stretch = 37 N
left-hand spring constant (k₁)= 2.7 N/cm
right hand spring constant(k₂)= 4.3 N/ cm
spring are connected in parallel
F = F₁ + F₂
F = k₁x + k₂x
F = (k₁+ k₂)x
37= (4.3+ 2.7)x
7 x = 37
x = 5.29 m
Answer:
Explanation:
Given,
mass of the bar = 1.1 Kg
length of rod, l = 0.40 m
diameter of the rod, d = 2 cm
frequency, f = 1.5 MHz
time, t = 0.12 ms
wavelength of the shock wave = ?
Speed of the wave =
v = 3333.33 m/s
wavelength of the wave
False, his first law states: An object that's in motion will remain in motion at a constant velocity unless it's acted on by an unbalanced force.
The initial velocity of the train is 12.56 m/s.
<h3>
Initial velocity</h3>
The initial velocity of the train can be determined by using the first kinematic equation as shown below;
v = u + at
u = v - at
where;
- v is the final velocity = 110 km/h = 30.56 m/s
- u is the initial velocity
u = 30.56 - (36 x 0.5)
u = 12.56 m/s
Thus, the initial velocity of the train is 12.56 m/s.

Explanation:
Recall that
so the speed of the bacterium is
Next, we convert this speed to km/hr. Recall that
Therefore,
