<span>Possible explanation one would be people are outdoors more due to the use of the snow blower and are thus more susceptible to falling as a result if the increased time spent near or on the ice. Possible explanation two is the snow that's removed from their sidewalk can no longer provide a traction surface between the people clearing the snow and the ice that lies beneath the snow. And possible explanation number three would be that the snow blowing machine, being a new piece of equipment to people, requires a level of agility to operate and inexperienced operators lack the agility to use the piece of equipment.</span>
Answer:
charge will be equal to
Explanation:
We have given mass of the particle m = 1.45 gram = 0.00145 kg
Acceleration due to gravity
Electric field E = 700 N/C
Electric force will be equal to , here q is charge and E is electric field
For particle to be stationary this force must be equal to force due to gravity , that is mg force
So qE = mg
So charge will be equal to
The temperature rises of in the block if the current flows for 10 minutes is, 34.78K.
To find the answer, we need to know about the power of the electric heater.
<h3>How to find the temperature rise of in the block if the current flows for 10 minutes?</h3>
- We have given with the variables,
- We have an expression the heat given to the system as,
ΔT
- We have to find the temperature rise ΔT,
ΔT
Thus, we can conclude that, the temperature rises in the block if the current flows for 10 minute is 34.78K.
