A drone flies upward with a velocity of 5m/s and has a kinetic energy of 90J What is the mass of the drone?
O 5.4 kg
1.9 kg
7.2 kg
3.6 kg
Answer:
m = 7.2 kg
Explanation:
Given that,
The velocity of the drone, v = 5 m/s
The kinetic energy of the drone, E = 90 J
We need to find the mass of the drone. The formula for the kinetic energy of an object is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 90}{(5)^2}\\\\m=7.2\ kg[/tex]
So, the mass of the drone is 7.2 kg.

The current in the wires of a circuit is 60.0 milliAmps. If the
voltage impressed across the ends of the circuit were
doubled and the resistance were tripled, then its new current
would be ___ milliAmps.
Answer:
I' = 40 mA
Explanation:
Given that,
The current in the wires of a circuit is 60.0 mA.
If the voltage impressed across the ends of the circuit were doubled and the resistance were tripled such that,
V' = 2V and R'=3R
The relation between current, voltage and resistance is given by :
V = IR
Let I' be the new current. So,
V'=I'R'
⇒ [tex]I'=\dfrac{V'}{R'}\\\\I'=\dfrac{2V}{3R}\\\\I'=\dfrac{2}{3}\times \dfrac{V}{R}\\\\I'=\dfrac{2}{3}\times I\\\\I'=\dfrac{2}{3}\times 60\\\\I'=40\ mA[/tex]
So, the new current would be 40 mA.

When drawing a vector, you should represent the magnitude of the vector by the length of the arrow. A. True O B. False
Answer: A. True
Explanation:
Answer:
A. True
Explanation:
A vector in this sense is a thing that has both magnitude (length) and direction.
Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.
This doesn't give any information about where you started or any information about where you ended up after those 2 hours.
This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.
Velocity is a vector.

A weightlifter lifts a set of weights a vertical distance of 2.0 m. If a constant net force of 350 N is exerted on the weights, what is the net work done on the weights?
Answer:
700 Joules
Explanation:
The work done equals force times distance. Just multiply your two values there.
Side note: It would be more impressive if he'd done it in 1 second rather than 5. You know why? Because POWER=WORK/TIME. The less time it takes him to lift the weight with the same force and distance, the more powerful he is!

What is the mass of a large ship that has a momentum of 1.60x10^9 kg*m/s and is moving at a velocity of 10m/s?
Answer:
160000000 kg.
Explanation:
p=mv
p=1.6x10^9
v=10m/s
rearrange and substitute:
(1.6x10^9)=m(10)
m=(1.6x10^9)/10
m= 1.6x10^8 kg.
One day, Pinki was ironing the clothes in her room. After half an hour of ironing, the light went off and Pinki went outside to the lobby of her house to check it there was any problem in the household circuit. At the same time, she listened the voice of her 4 years old daughter from the same room where she was ironing the clothes. Her daughter was about to touch the hot electric iron but at the same moment, Pinki entered in the room and pushed her daughter back from that place.
(a) On which effect of electric current, does the electric iron works?
(b)State the effect of electric current described here.
(c) Mention the values showed by Pinki here.
PLEASE ANSWER ASAP
Answer:
(a) An electric iron works on the heating effect of electric current
(b) The heating effect of an electric current is the tendency for electric current to cause the temperature of the material through which it is flowing to rise due to the resistance of the material
The heating effect, 'E', is given by the formula, E = I²·R·t
Where;
I = The current flowing
R = The resistance of the material
t = The time the material takes to heat up
(c) The values showed by Pinki here is the value of care, concern and prevention, to prevent the harmful effect of the high heat on the skin of her daughter

Answer: 5 amps
Explanation: I = Q/t
Which of these is not a standard unit?
a. second
b. metre
c. hand span
d. gram
Answer: Hand span
Explanation: Hand span is not a standard unit.
Second is the unit of time.
Meter is the unit of length or distance covered by an object.
Gram is the unit of weight of an object.
Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".
A sodium vapor lamp omit waves with the frequency of 5.26x10^14 Hz. What is the wavelength of light?
Answer:
[tex]\lambda=5.70\times 10^{-7}\ m[/tex]
Explanation:
The frequency of a sodium vapor lamp, [tex]f=5.26\times 10^{14}\ Hz[/tex]
We need to find the wavelength of light. The relation between wavelength, frequency and speed of light is given by :
[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{5.26\times 10^{14}}\\\\\lambda=5.70\times 10^{-7}\ m[/tex]
So, the wavelength of light is equal to [tex]5.70\times 10^{-7}\ m[/tex].
How fast is a skydiver going after 5 seconds or free fall and how far did he fall
Answer:
It's typically around 120mph. You'll reach this speed a few seconds into your jump, so for those few moments straight out the door, you'll be falling a bit more slowly and therefore covering less distance. We usually estimate around 10 seconds for the first 1,000 feet, then 5 seconds for each 1,000 feet after that.

How far does a sound wave travel in 3 seconds if the air temperature is 30 degrees
Celsius?
a) 114.33 m
b) 1047 m
c) 1029 m
d) 116.33 m
Answer:
B
Explanation:
v=349m/s
d=vt
d=349*3
d=1047m
WHY 349??
Because, velocity of sound increases about 0.6 m/s for every 1 degree celsius rise in temp.
Velocity of sound is about 343 m/s at 20 degrees C, so 0.6*10=6 more m/s, or 349 m/s. Kinda cool how temperature alters the speed of sound!

Are acceleration and mass proportional or inversely proportional values?
Answer:
acceleration and mass are inversely proportional values
Explanation:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Each bat can produce different frequencies of ultrasound. Explain why this is useful if there are many bats hunting together.
Answer: Although low frequency sound travels further than high-frequency sound, calls at higher frequencies give the bats more detailed information--such as size, range, position, speed and direction of a prey's flight. Thus, these sounds are used more often.
