<span>Higher temperature means greater kinetic energy, which means the warmer block has greater thermal energy.

Answer:
20 N.
Explanation:
The following data were obtained from the question:
Mass of block B (m) = 2 Kg
Acceleration due to gravity (g) = 10 m/s²
Gravitational force (F) =..?
Force is simply defined as the product of mass and acceleration i.e
Force = mass (m) × acceleration (a)
F = ma
Thus, we can say that the gravitational force on block B will be the product of the mass of block B and acceleration due to gravity i.e
Gravitational force (F) = mass of block B (m) × acceleration due to gravity (g)
F = mg
Mass of block B (m) = 2 Kg
Acceleration due to gravity (g) = 10 m/s²
Gravitational force (F) =..?
F = mg
F = 2 × 10
F = 20 N
The, the gravitational force exerted on block B is 20 N
In short, and in general:
Advantages
<span>Credit Unions typically pay higher dividend rates on savingsCredit Unions typically offer lower rates on loansCredit Unions typically provide better service; since they are owned and governed by their membership, they tend to prioritize the needs of their members above all elseCredit Unions operate on a not-for-profit business model, so excess earnings are returned back to the membership in form of competitive rates and lower fees, and sometimes even special dividendsMany Credit Unions offer the same products and services found at banksCredit Unions often have added-value benefits, such as free financial education, discounted theme park tickets, and special member rates for services such as home alarm systems...even discounts at online retailers like Barnes & Noble.</span>Disadvantages
<span>Credit Unions, and in particular smaller local credit unions, struggle to match the level of convenience (ATMs and branches) that many banks provide their customers, although many CUs are part of shared networks which enhance the breadth of delivery channels available to their membersSome Credit Unions are limited in their product offeringsOne must qualify for membership <span>One must pay a membership fee to join. hope this helps!

Weight is the force exerted on an object by gravity. So, weight of any object on the moon is 1/6 that on Earth.
Answer:
6.575
Explanation:
T1 = 30C = 30 + 273 = 303 K
T2 = - 10 C = - 10 + 273 = 263 K
The coefficient of performance of heat pump
k = T2 / (T1 - T2)
k = 263 / (303 - 263) = 6.575
