Answer:
=30.22°C
Explanation:
The enthalpy change made the water to cool.
Enthalpy change = MC∅ where M is the mass of the water, C is the specific heat capacity of water and ∅ the temperature change.
ΔH=MC∅
∅=ΔH/MC
=(6.3×10⁴J)/(0.5kg×4186J/(kg°C))
=30.1
Final temperature = 35.00°C-30.1°C
=4.9°C
The answer will be 50N.
This is because the spring reads weight and weight is mass times acceleration due to gravity.5kg*10m/s2=50N
Answer:
Susie has strabismus.
Explanation:
Strabismus is a medical condition in which the patient can not keep his/her eyes aligned under the normal conditions. In strabismus one or both of eyes rolls into up, down, in or out direction. Physicians usually recommend the exercises for eyes or placing a patch on the unaffected eye or they also do surgery where it's required like in severe cases.
It will float because the density is less than 1
I think the answer should be the last one. Magnets attract magnets with unlike poles and repel magnets with like poles
