<h2>The height of the room is 36 m </h2>
Explanation:
The time period of the pendulum T = 2π
here l is the length of pendulum and g is the acceleration of gravity
Thus l = 
and l = 
= 36 m approx
E=mc^2 n its given 1kg = 9x10^16J
so need to figure out the total mass loss n u can find the energy released
mass loss when 4x H atom combines to form 1x He atom in a fusion reaction is given as 4.59x10^-29kg
1 mole of He has 6.02x10^23 He atoms
so 2.7 moles of He has 2.7x6.02x10^23 He atoms
the total mass loss for 2.7 moles of He created in a fusion reaction
= 2.7x6.02x10^23 x 4.59x10^-29kg
= 7.46x10^-5kg
radiation energy released from this fusion reaction
= 7.46x10^-5 x 9x10^16J
= 6.7x10^12J
its 60 BILLION times more than burning carbon!!
The Hydronium ion concentration increases to 100 times the original concentration (10^2)
Answer:
N = 1364 N
Explanation:
given data
accelerate upward = 5.70 m/s²
mass = 88.0 kg
solution
normal force is in upward direction so, weight of the student in downward direction and acceleration is in upward direction so formula is express as
N - mg = ma ...........................1
N = m × (g+a)
put here value
N = 88.0 × (9.8 + 5.70)
N = 1364 N
Answer:
A
Explanation
i think its a not 100% sure though.
