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
Answer:
864 KN
Explanation:
(Absolute pressure) = (Atmospheric pressure) + (Gauge Pressure)
Atmospheric pressure = 95 KPa = 95000 Pa
Gauge Pressure = ρgh
ρ = density of the fluid = 1000 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = depth below the fluid level that the object is at = 5 m
Gauge Pressure = 1000 × 9.8 × 5 = 49000 Pa
Absolute pressure = 95000 + 49000 = 144000 Pa.
Pressure = (Hydrostatic force)/(Area perpendicular to the force)
Hydrostatic force = (Pressure) × (Area perpendicular to the force)
Area perpendicular to the force = 2 × 3 = 6 m²
Hydrostatic force on the top of the plate = 144000 × 6 = 864000 N = 864 KN
Hope this Helps!!!
Answer:
741.333
Explanation:
F = ma
so in order to find mass you must change the equation to
m = F/a
m = 5560/7.5
741.333 = 5560/7.5
Conduction occurs when a substance is transferring heat via touching.
Convention occurs when the substance being heated begins a cycle of cooling and heating. the heat goes to the opposite side of which the substance is being heated and the substance is cooled on the corresponding side, this cycle continues until the heat source is extinguished.
Radiation occurs when the heat of a substance is being transferred via gas form. Ex: sunburn.
The vertical velocity of the ball is:
. Since gravity acts at
, this means that the time of flight up to the maximum height (at which vertical velocity is 0) would be:
This maximum height is:
Then the time for it to fall down will be:
The total time will be 3.69 + 3.73 = 7.42 seconds.
