Solution= The answer is true
Answer:
<h2>
work done= 48.96 kJ</h2>
Explanation:
Given data
mass of load m= 425 kg
height/distance h=64 m
acceleration a= 1.8 m/s^2
The work done can be calculated using the expression
work done= force* distance
but force= mass *acceleration
hence work done= 425*1.8*64= 48,960 J
work done= 48.96 kJ
Answer:
1270 segundos
Explanation:
Dada,
Velocidad ( v ) = 3810 m/s
Distancia ( s ) = 3 m
Encontrar : -
Tiempo que tarda el sonido en viajar ( t ) = ?
Fórmula : -
s = d / t
t = d / s
= 3810 / 3
t = 1270 segundos
There will be 0.125g (1/8th) left of that radioactive substance by 3:00pm
12:00 = 1g
1:00 = 0.5g
2:00 = 0.25g
3:00 = 0.125g
