Answer:
<em>a. q=450 c
</em>
<em>b. E=675 J
</em>
Explanation:
<u>Direct Current (DC)
</u>
It's the flow of electric charges in one direction driven by a constant voltage circuit. The intensity of the current flow is computed as
Where q is the constant flow of charge in time t
The energy of an element providing Voltage V, current I during a time t is
a. The charge can be computed by solving the first equation for q
b. The energy transferred by the battery is
Samburu's weight is (mass x gravity) = (1650kg x 9.8 m/s²) = 16,170 Newtons.
Samburu's contact area with the ground is (0.25 m²/hoof) x (4 hoofs) = 1 m² .
Pressure = (force) / (area) = (16,170 Newtons) / (1 m²) = 16,170 Pascal .
Answer:
The volume is
Explanation:
From the question we are told that
The depth below the see is
The density of the sea is
The temperature at this level is
The volume of the air bubble at this depth is
The temperature at the surface is
Generally the pressure at the given depth is mathematically evaluated as
Where is the atmospheric pressure with a constant value
substituting values
According to the combined gas law
=>
=>
Answer:
t = 66.7 s
Explanation:
Given that,
Speed of a hare, v = 15 m/s
Speed of a turbocharged tortoise, v' = 3 m/s
The hare in a 250 meter race
Let the Hare takes time t. It can be calculated as follows :
Let a turbocharged tortoise takes t'. It can be calulated as follows :
To tie the race, required time is given by :
Hence, the correct option is (b) i.e. 66.7 seconds.
