Answer:
I believe that it will be 10kg of water
Explanation:
Because a measure of the amount of information on a storage medium (tape or disk). For magnetic tape it is the amount of information recorded per unit length of tape (bits per inch or millimeter); for a disk, a fixed number of bits per sector, sectors per track, and tracks per disk.
The density in both the case will be equal, just the difference will be in the volume they occupy.
What is density?In practice, density is the weight of a substance per unit volume. Water has a density of about 1 gram per milliliter, but this varies depending on temperature and whether or not substances are dissolved in it. Because ice is less dense than liquid water, it floats in your glass.
This allows many aquatic organisms to survive the winter. If ice were more dense than water, it would continue to freeze and sink until the entire lake was frozen.
Any amount of water has the same density. Whereas one gram of water has a volume of one milliliter, ten grams have a volume of ten milliliters.
Thus, the density will be same.

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.
Explanation:
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.

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

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].

A car manufacturer wants to change its car’s design to increase the car’s acceleration. Which changes should the engineers consider making to the design? increase the force that the engine provides decrease the force that the engine provides increase the mass of the car decrease the mass of the car increase the top velocity the car can travel decrease the top velocity the car can travel
Answer:
I. increase the force that the engine provides.
II. decrease the mass of the car
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
[tex] Acceleration = \frac {Force}{mass} [/tex]
In this scenario, a car manufacturer wants to change its car’s design to increase the car’s acceleration. Thus, the changes the engineers should consider making to the design is to increase the force that the engine provides and decrease the mass of the car.

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!

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".
