A toaster uses 6700 joules of energy in 45 seconds to toast to a piece of bread what is power of the oven
just olya [345]
P= w/t and W= Work 
In this case, W= 6,700j, and T= 45 seconds
Power is the ratio of work  per unit time. When you perform a work in a given span of time, the ratio of work performed with respect to time is Called Power. 
si unit for Power is Watt (W) 
so, P= 6,700/45
P= 148 
Final answer is P=148

The length of the mercury thread is found to be 4cm and 24cm at ice point and steam point respectively on an ungraduated thermom
BabaBlast [244]

Answer:

The difference between ice and steam in Celsius (Centigrade) is 100 deg.

So the difference between and 4 cm and 24 cm of the thread corresponds to 100 deg C.

So 8 cm is 4 cm greater than the ice point

4 cm / 20 cm = 1/5     since the steam point and the ice point are 20 cm apart

Then 1/5 * 100  deg C = 20 deg C   the requested temperature
