Answer:
10 400 N
Explanation:
A drag force is an oppositional or limiting force which must be overcome before an object must move wit a force. The lesser the drag force, the higher the probability that an object would move easily.
From the question give, the resultant force of the was is 600 N and force from the engine - 11 000 N.
Drag force = 11 000 - 600
= 10 400 N
The drag force on the car is 10 400 N.
This shows that the car would not move since the drag force (10 400 N) is far greater than the resultant force(600 N).
Carbon monoxide (CO) is an odorless, poisonous gas. It is evolved from combustion engines. In boats, carbon monoxide is released near the engines when fuels like gasoline are combusted. CO is also released in the exhaust of the generators used on board. High concentrations of CO are situated at the exhaust outlets in the boats. Carbon monoxide poisoning in boats can be prevented by having proper ventilation system in the boat.
Explanation:
The pH of a substance can be found by using the formula
where [ H+ ] is the hydrogen ion concentration in the substance
From the question
[ H+ ] = 2.1 × 10-¹² M
To find the pH substitute the value into the above formula
We have
We have the answer as
<h2>pH = 11.7 </h2>
The solution is basic since it lies in the basic region that is from 8 to 14
Hope this helps you
The energy which is required to split a nucleus into its discrete neutrons and protons is said to be nuclear binding energy.
Using the formula for nuclear binding energy:
E = Δmc²
where,
E = nuclear binding energy
Δm = mass defect
c = speed of light
Substitute the given value of mass defect and speed of light in above formula:
E =
E =
= Joule.
E=
Thus, nuclear binding energy of an atom is .
