Kinetic Energy of particle of mass, m moving with velocity, v is
K.E. = ½mv²
m= 1500 kg
v = 10 m/s
((1/2)*1500)*
750*10=75000
KE=75 joules
How can you figure out kinetic energy?
According to classical physics, kinetic energy (KE) is determined by multiplying an object's mass by its velocity squared, or half of the mass (1/2*m). The kinetic energy of an object with a mass of 10 kilograms (m = 10 kg) travelling at a speed of 5 m/s (v = 5 m/s) is equal to 125 joules, or (1/2 * 10 kg) * 5 m/s2.
a vehicle with a mass of 1200 kg and a speed of 20 m/s. KE = ½mv 2
KE = ½ x 1200 x (400) = 240,000 J 2.

Hello!
If The 1500 kg car will increase its velocity to 10 m/s. What Will be its kinetic energy ?
We have the following data:
m (mass) = 1500 kg
v (velocity) = 10 m/s
KE (kinetic Energy) = ? (in Joule)
Formula to calculate kinetic energy:

cesium (Cs)
fluorine (F)
boron (B)
Answer: Cesium (Cs)
Explanation:
Elements lose or gain electrons in their valence shell so as to maintain stability by either forming duplets or octet configuration. I.e 2 electrons in its outer shell to form duplet or 8 in its outer shell to form octet configurations. All metals with exception of Metalloids lose electrons in its outer shell corresponding to its group number to form stability. I.e group 1 elements lose 1 electrons to form stability, group two elements lose 2 electrons, group 3 and so on. From the elements listed above, Cesium is a group 1 element and it will require to lose 1 electron so as to form stability. Magnesium (Mg) loses 2 electrons to form stability, Fluorine (F) a non metal from group (vii) requires 1 electron to be stable and boron a group (v) element would need 3 electrons to form stability.
Answer:
Hey!
Your answer is element A
Explanation:
Using the graph, the element A's emission of radioactive particles ends approximately after 6 years...
A HALF-LIFE IS "HALF" OF THAT TIME PERIOD!
So if the radiation goes for 6 years the half-life is 6 divided by two which gives you 3 years!
The rest however have a longer half-life...
Because they all end at 14 yrs so their half-life in 7 years!
HOPE THIS HELPS!!
