Evgesh-ka [11]3 years ago
5 0

Answer:

90000J

Explanation:

Given parameter:

Power of the microwave = 1000watt

time for soup to heat = 90s

Unknown:

Amount of energy delivered = ?

Solution:

Electric power is the rate at which electrical energy is transferred.

  Electrical power = \frac{electrical energy}{time}

 Electrical energy = electrical power x time

input the variables;

 Electrical energy = 1000 x 90 = 90000J

const2013 [10]

The magnitude and direction of half of the given vector A is 1.25 m east.

The given parameters;

  • <em>magnitude of vector A = 2.5 m east</em>

A vector can be described with both magnitude and direction. The magnitude of the vector is the scalar or numeric representation of the vector.

When the scalar representation has direction, we term the quantity a vector quantity.

The magnitude of half of the given vector is calculated as follows;

\frac{A}{2} = \frac{2.5 \ m}{2} = 1.25 \ m\ east

Thus, the magnitude and direction of half of the given vector A is 1.25 m east.

Inessa05 [86]

Initial velocity=u=15m/s

Final velocity=v=10m/s

Time=0.08s

\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}

\\ \sf\longmapsto Acceleration=\dfrac{10-15}{0.08}

\\ \sf\longmapsto Acceleration=\dfrac{-5}{0.08}

\\ \sf\longmapsto Acceleration=-62.5m/s^2
