Answer:

-5 m/s^2

Explanation:

acceleration =  \frac{change \: in \: velocity}{time}  \\  \\  =  \frac{15 - 25}{2}  \\  \\  =  \frac{ - 10}{2}   \\  \\  =  -  5 \: m {s}^{ - 2}  \\  \\ negative \: sign \: represents \: that \:  \\ object \: is \: slowing \: down.

Explanation:

Acceleration is the change in velocity over time.

a = Δv / Δt

a = (15 m/s − 25 m/s) / 2.0 s

a = -5.0 m/s²

The magnitude of the acceleration is 5.0 m/s².

An electric field of intensity 3.7 kN/C is applied along the x-axis. Calculate the electric flux through a rectangular plane 0.3
jekas [21]

Answer:

a)906.5 Nm^2/C

b) 0

c) 742.56132 N•m^2/C

Explanation:

a) The plane is parallel to the yz-plane.

We know that

flux ∅= EAcosθ

3.7×1000×0.350×0.700=906.5 N•m^2/C

(b) The plane is parallel to the xy-plane.

here theta = 90 degree

therefore,

0  N•m^2/C

(c) The plane contains the y-axis, and its normal makes an angle of 35.0° with the x-axis.

therefore, applying the flux formula we get

3.7×1000×0.3500×0.700×cos35°= 742.56132 N•m^2/C

brainly an electric heating element is connected to a 110V circuit and a current of 3.2A is flowing through the element. how muc
Naya [18.7K]

Energy used by the element = 6336000 j

The electrical energy is given by

E= V i t

V= voltage= 110 V

i= current=3.2 A

t= time= 5 h= 5 (3600)= 18000 s

so energy= E= 110 (3.2)(18000)

E=6336000 J
