Answer:
B.
Explanation:
The elastic potential energy of the spriy at position 2 is converted to kinetic energy.
Answer:
No it's different for different objects because they made of different materials
Answer:
Afterdrop is the phenomenon of your body temperature continue to drop even after you get out of cold water and into a warmer environment – so that you feel colder 10 or 40 minutes after you exit than you did in the water. When you swim, your body shuts down circulation to your skin, pooling warm blood in your core.
Answer:
option (c)
Explanation:
According to the doppler's effect, the frequency of sound decreases.
If there is a relative motion between the source and the observer, the frequency of sound changes apparently.
the formula of the doppler effect is given by
where, f is the real frequency, v be the speed of sound, vo be the speed of the observer, here, the bus is the observer.
So, the value of f' < f
A = 94
B = 36
C = Kr or Krypton
Explanation:
The given nuclear reaction is written below:
²³⁵₉₂ U + ₀¹ n ⇒ ¹³⁹₅₆Ba + ᵃₙ C + 3¹₀n
Although mass and matter is not conserved in nuclear equations, the mass and atomic number must be conserved.
This implies that the mass number on both side of the equation be the same. The atomic number too must be the same.
Conserving mass number;
235 + 1 = 139 + a + 3(1)
a = 236 - 142 = 94
Conserving atomic number:
92 + 0 = 56 + n + 3(0)
92 = 56 + n
n = 36
A = 94
B = 36
C = Kr or Krypton
