It does. When you are doing sit ups, it makes your core work and if you have a good strong core then you are burning fat. <span />

When an object with a negative charge is moved from point A to point B through an external electrical field, it gains electrical
Sergio039 [100]

Explanation:

As per the problem,

           \Delta U = (V_{B} - V_{A})(-q) > 0

When q > 0 then -q is a negative charge . Since, change in potential energy (\Delta U) increases.

or,     (V_{A} - V_{B})q > 0

or,      V_{A} > V_{B}

Therefore, both positive and negative charge will move from V_{A} to V_{B} and as V_{B} < V_{A} so both of them move through a negative potential difference.

Thus, we can conclude that the true statements are as follows.

  • The positively charged object moves through a negative potential difference between A and B (that is, VB - VA < 0).
  • The negatively charged object moves through a negative potential difference between A and B (that is, VB - VA < 0).

Mary and her younger brother Alex decide to ride the 26 ft diameter carousel at the State Fair. Mary sits on one of the horses i
hammer [34]

Answer:

a_M=1.92a_A

Explanation:

\omega_M=\omega_A = Angular speed

r_M = Distance of Mary = 11.5 ft

r_A = Distance of Alex = 6 ft

Ratio of centripetal acceleration is given by

\dfrac{a_M}{a_A}=\dfrac{\omega_M^2r_M}{\omega_A^2r_A}\\\Rightarrow \dfrac{a_M}{a_A}=\dfrac{r_M}{r_A}\\\Rightarrow a_M=a_A\dfrac{r_M}{r_A}\\\Rightarrow a_M=\dfrac{11.5}{6}a_A\\\Rightarrow a_M=1.92a_A

Mary's centripetal acceleration is 1.92 times the centripetal acceleration of Alex
