The wave height is equal to twice the amplitude of the wave.

The wave height of a wave of given wave with amplitude, period and wavelength is equal to twice the amplitude of the wave.

The amplitude of a wave is the maximum displacement of the wave, starting from the zero position of the wave. The wave height measures twice the maximum displacement of the wave.

Thus, we can conclude that the wave height is equal to twice the amplitude of the wave.

On a spacecraft, two engines are turned on for 684 s at a moment when the velocity of the craft has x and y components of v0x 43

Natasha2012 [34]

As we know by the kinematics

$\delta x = v_x * t + \frac{1}{2} at^2$

$4.11106 = 4370* 684 + \frac{1}{2}a_x*684^2$

$4.11106 = 2989080 + 233928*a_x$

$a_x = -12.78 m/s^2$

Similarly for Y direction

$\delta y = v_y * t + \frac{1}{2} at^2$

$6.07106 = 6280* 684 + \frac{1}{2}a_y*684^2$

$6.07106 = 4295520 + 233928*a_y$

$a_y = -18.36 m/s^2$

A 5,000 Kg monster truck is traveling at 11 m/s. when it sees an obstacle it is going to crush during the Monster truck rally, i

avanturin [10]

The change in the kinetic energy of the monster truck during the time is 507500 J and the right option is B). 507500

<h3>What is kinetic energy?</h3>

Kinetic energy is the energy of a body due to its motion.

To calculate the increase in the kinetic energy of the monster truck, we use the formula below.

Formula:

ΔK.E = m(v²-u²)/2............. Equation 1

Where:

ΔK.E = Increase in kinetic energy of the monster truck
m = mass of the monster truck
v = final velocity of the monster truck
u = initial velocity of the monster truck.

From the question,

Given:

m = 5000 kg
v = 18 m/s
u = 11 m/s.

Substitute these values into equation 1

ΔK.E = 5000(18²-11²)/2
ΔK.E = 2500(324-121)
ΔK.E = 2500(203
ΔK.E = 507500 J

Hence, The increase in the kinetic energy of the monster truck during the time is 507500 J and the right option is B). 507500.

Bad White [126]

Answer:

The answer is <em>15A</em>

Explanation:

Terminal of like polarity are connected with jumpers of negligible resistance

Kirchoff's voltage law gives

E1 -E2 - IR1 - IR2 = 0

I(R1 + R20 = E1 -E2

I= 12 -9/ 0.18 + O.2 = 15A OF CURRENT WILL FLOW THROUGH DISCHARGED BATTERY.
