Simply,
To figure out the speed the car traveled to get 540km from point A in 6 hours, You’d have to solve 540 divided by 6.
540 divided by 6 = 90
So the answer would be 90km per hour,
Assuming you want the answer in km.
Answer:
water leak is 650 gallons
time required to full drain is 80 hrs
Explanation:
given data
volume V = 3200 gallon
rate = V(t) = 80 - t
to find out
how much water leak between 10 and 20 hour and drain complete
solution
we know here rate is 80 - t
so here rate will be
= 80 - t
and for time 10 and 20 hour
take integrate between 10 and 20
so water leak = 
.....................1
water leak = ( 80t - 
water leak = 650
so water leak is 650 gallons
and
we know here for full tank drain condition
water leak full = 80 t - 
3200 = 80 t -
6400 = t² - 160 t
t = 80
so time required to full drain is 80 hrs
<h3><u>Answer;</u></h3>
Energy
<h3><u>Explanation;</u></h3>
- A wave is a transmission of disturbance from one point to another. All waves involve transmission of energy from one point called the source to another point.
- <em><u>Waves describes various ways in which energy can be transferred from a point source.</u></em>
- <em><u>In electromagnetic waves</u></em><em>, for instance, </em><em><u>energy transmission occurs as a result of vibrations of electric and magnetic fields</u></em><u>.</u>
- <u><em>In mechanical waves energy transmission is as a result of vibration of particles in the medium used</em></u>. For example in sound waves, energy is transferred through vibration of particles of air or particles of a solid or medium through which sound travels through.
Answer:
2. False :
- An object that is positively charged has a greater positive charge and a lower negative charge.
3. Will be This :
Q.→ TRUE or FALSE: An object that is negatively charged could contain only electrons with <u>no</u> accompanying protons.
Answer → False :
- Negatively charged objects have protons; it's just their number of electrons is greater than their number of protons.
4. False :
- An object that is electrically neutral contains neutrons and the same number of unlike charges, i.e., electrons and protons.
Answer:
horizontal component=fcostita
=150cos60
use calculator to evaluate it
for vertical=fsintita
=150sin60
