Answer:

The acceleration of a ball is 5 m/s².

Explanation:

Given that,

Initial velocity = 20 m/s

Time = 2.0 sec

Final velocity = 30 m/s

We need to calculate the acceleration

Using equation of motion

v =u+at

a =\dfrac{v-u}{t}

Where, v = final velocity

u = initial velocity

t = time

Put the value into the formula

a =\dfrac{30-20}{2.0}

a=5\ m/s^2

Hence, The acceleration of a ball is 5 m/s².

What percentage of the acceleration at Earth's surface is the acceleration due to gravity at the position of a satellite located
lana66690 [7]

Answer:

Explanation:

The formula for variation in the value of g due to height h is given by the following relation .

g₁ = g₀ ( 1 - h / R )

g₁ and  g₀ are value of acceleration due to gravity at height h from surface and at surface and  R is radius of the earth .

R = 6370 km , h = 489 km ( given )

g₁ = g₀ ( 1 - 489 / 6370 )

= .923 g₀

g₁ in percent terms = .923 x 100

= 92.3 % .

How is heat related to phase changes​
bekas [8.4K]

The heat is used to break the bonds between the ice molecules as they turn into a liquid phase. Since the average kinetic energy of the molecules does not change at the moment of melting, the temperature of the molecules does not change.
