Explanation:

The velocity of the watermelon as it hits the ground is 14.715 m/s.

Given the data in the question;

Since the Watermelon was dropped from rest,

Now, we determine the velocity of the watermelon as it hits the ground which is the final velocity.

From the First Equation of Motion:

[tex]v = u + at[/tex]

Now, under gravity, acceleration ''a" will Acceleration due to gravity;[tex]g = 9.81m/s^2[/tex], "v" is the final velocity, "u" is the initial velocity and "t" is the time taken.

So, we substitute our values into the equation

[tex]v = 0m/s\ +\ ( 9.81m/s^2\ * 1.5s )\\\\v = ( 9.81m/s^2\ * 1.5s )\\\\v = 14.715 m/s[/tex]

Therefore, the velocity of the watermelon as it hits the ground is 14.715 m/s

Hi there!

We can solve this in two ways, using the Work-Energy theorem or kinematics.

Work-Energy:

We know that:

Ei = Ef, as long as there are no external forces working on the system.

Thus:

Ei = PE = mgh

Ef = KE = 1/2mv²

Therefore:

mgh = 1/2mv²

We can cancel out the mass:

gh = 1/2v²

9.8(10) = 1/2v²

√196 = v = 14 m/s

We can also solve using kinematics, using the equation:

vf² = vi² + 2ad

From rest (vi = 0 m/s) and a = g, so:

vf² = 2gd

vf = √2gh

vf = √(2 × 9.8 × 10) = 14 m/s

Answer:

How do X rays use electromagnetic waves to function?

X-rays are very high-frequency waves and carry a lot of energy. They will pass through most substances, making them useful in medicine and industry to see inside things. An X-ray machine works by firing a beam of electrons at a "target." If we fire the electrons with enough energy, X-rays will be produced.

Answer:

0.12kg / 0.19

Explanation:

Becase the volcity reuded

The final velocity of the 0.18 kg object after the collision is 0.19 m/s in the same direction as the object which strikes it, then the initial velocity of the 0.12 kg object would be 0.237 m / s .

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

As given in the problem, a 0.12 kg object makes an elastic head-on collision with a 0.18 kg stationary object. The final velocity of the 0.12 kg object after the collision is 0.048 m/s in the direction opposite its initial movement. The final velocity of the 0.18 kg object after the collision is 0.19 m/s in the same direction as the object which strikes it.

By using the conservation of the momentum,

v × 0.12 + 0 × 0.18 = ( - 0.048)× 0.12 + 0.19 × 0.18

v = 0.237 m / s

Thus, the initial velocity of the 0.12 kg object would be 0.237 m / s .

#SPJ2

Answer: see below

Explanation:

The intial speed is u=0[tex]\frac{m}{s}[/tex]

The acceleration is a= 3.3[tex]\frac{m}{s}^2[/tex]

The distance is s=60m

Apply the equation of motion

[tex]v^{2}[/tex]=[tex]u^{2}[/tex]+2as

So,

[tex]v^{2}[/tex]=0+2*3.3*60=396

v=[tex]\sqrt{396}[/tex] = 19.89 m/s ≈20 m/s

Applying the equation of motion

v=u+at

t= [tex]\frac{v-u}{a}[/tex] =[tex]\frac{19.89-0}{3.3}[/tex] = 6.02seconds

Answer:

B. 5Ω

Explanation:

Equivalent resistance between point P and Q

= 3Ω + Tp

Total Parallel resistance, Tp

[tex] \frac{1}{Tp} = \frac{1}{12Ω} + \frac{1}{6Ω} + \frac{1}{4Ω} [/tex]

[tex]\frac{1}{Tp} = \frac{1}{12Ω} + \frac{2}{12Ω} + \frac{3}{12Ω} [/tex]

[tex]\frac{1}{Tp} = \frac{6}{12Ω}[/tex]

[tex]6(Tp) = 12Ω[/tex]

[tex]Tp = \frac{12Ω}{6} [/tex]

[tex]Tp = 2Ω[/tex]

Equivalent resistance between point P and Q
