Answer:
35.7 kg
Explanation:
We are given that
Left scale reads =200N
Right scale reads=150 N
We have to find the mass in kg.
We know that
Weight of child= Sum of two scales=200+150=350 N
Acceleration due to gravity=
We know that
Weight= mg
Using the formula
Hence, the mass of child=35.7 kg
Look for scientific research about whether these claims are correct or not.
Explanation:
The best thing to do after reading this advertisement is to look for scientific research about whether these claims are correct or not.
The kinetic energy of an object is given by:
where m is the mass of the object and v its velocity.
The car in this problem has a mass of m=600 kg and a velocity of v=10 m/s, therefore if we put these numbers into the equation, we find the kinetic energy of the car:
It’s B lovey !!! Glad to help
Answer:
volume of gas is 6.10 L
Explanation:
Given data
temperature = 730 K
pressure = 98 atm
pressure = 94 atm
gas = 10 moles
to find out
volume of gas
solution
we will apply here formula that is
PV = n RT
here P = 98 , n =10 , R = 0.082 and T = 730
put all these value we get Volume v
Volume = 10 (0.082) 730 / 98
volume = 598.6 / 98
volume = 6.108163265
so volume of gas is 6.10 L
