natita [175]

Explanation:

if two vectors are perpendicular to each other then thier dot product is equal to zero so (2i+3j+8k).(-4i+4j+ak)=0 (2)(-4) +(3)(4)+(8)(a) =0 -8+12+8a=0 4+8a=0 8a=-4

$a = \frac{ - 4}{8}$

$a = \frac{ - 1}{2}$

PSYCHO15rus [73]

Some of the energy is converted into heat. This is the main reason why electrical material gets hot when connected to a source. Therefore, your initial energy does not equal final energy. This does not violated energy conservation law because the energy is being converted so it is never lost.

How to calculate energy needed for a change of state

Alenkasestr [34]

Answer:

change in temperature = (100 - 25) = 75.0°C.

change in thermal energy = mass × specific heat capacity × change in temperature.

= 0.200 × 4,180 × 75.0.

= 62,700 J (62.7kJ)
