Answer:
The answer to your question is Q = 10.5 J
Explanation:
Data
C = 4.180 J/kgK
mass = 50 g
Temperature 1 = 298°K
Temperature 2 = 348°K
Formula
Q = mCΔT
Process
1.- Calculate ΔT
ΔT = Temperature 2 - Temperature 1
ΔT = 348 - 298
ΔT = 50°K
2.- Convert g to kg
1000 g -------------- 1 kg
50 g ------------- x
x = (50 x 1)/ 1000
x = 0.05 kg
3.- Substitution
Q = (0.05)(4.180)(50)
4.- Simplification
Q = 10.45 J
5.- Result
Q = 10.5 J
Answer:
Option C is correct.
Explanation:
Force between two charges = k q₁q₂ / r² , k is constant q₁ , q₂ are charges with separation of r .
= (9 x 10⁹ x 2.5 x 10⁻⁵ x 2.5 x 10⁻⁵) / .5²
= 56.25 x 10⁻¹ / .25
= 22.5 N
23 N .
Force will be attractive as the charges are opposite in nature .

18 In free fall you are being pulled by a gravity. "Truly" weightless presumably happens in deep space where there is nothing to pull you.
19 coasters accelerate down to simulate weight loss/zeroised. As do NASA planes,
Roller coasters are for fun seekers. NASA is for science
