Answer: Not enough information here at all!
Could be 195 2.5$ tickets and 8 4$ tickets and many more answers
Step-by-step explanation:
Answer:
Option C is correct.
Step-by-step explanation:
C- Survey every tenth student entering the school one morning.
This is because the survey is related to the entire student population of a school as they want to know which type of speaker the students prefer to invite to an assembly.
Reasons for incorrect options:
Option A is not true as it will relate to a mall survey. Option B is also incorrect as it will only survey few students of a student council that cannot represent a whole population. Option D is related to basketball survey, it has nothing to do with any speaker chosen for an assembly.
energy is always transformed from one form to another
energy is not created nor destroyed
so when a car starts moving the chemical potential energy of the car is converted to kinetic energy
kinetic energy is the energy that moving objects possess
kinetic energy formula is as follows
Kinetic energy = 1/2 mv²
where m - mass
v - velocity
substituting these values
K.E = 1/2 x 1350 kg x (12 m/s)²
= 1/2 x 1350 x 144 = 97200 J
the kinetic energy of the car is 97.2 kJ
Hello!
A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?
We have the following data:
m (mass) = 1350 kg
v (velocity) = 12 m/s
KE (kinetic Energy) = ? (in Joule)
Formula to calculate kinetic energy:
Solving:
