Metals such as aluminum can be formed into thin sheets because they are
Korvikt [17]

Answer:

They are malleable.

Explanation:

Malleability is the property of metals that causes them to be able to be formed into thin sheets without breaking.

All metals are malleable.

The reason why metals are malleable is because the atoms in the metals have a stable structure and hence, when beaten, the atoms can move freely among each other and maintain their structure.

Which of the following is the best example of kinetic energy being transformed into potential energy
poizon [28]

A pendulum is probably the most common showing of this example. As the pendulum swings down, it converts its potential energy (height) into kinetic energy (velocity). At the lowest point the kinetic energy is the highest and the potential is the lowest. At the highest point in its swing the velocity is zero so the kinetic energy is zero and the potential energy is at a maximum (greatest height).

You are a nurse in a hospital. You are told to move a patient through three corridors each measuring 14.33 meters. Because of fr
dimulka [17.4K]

Work done by force is given by formula

W = F.d

now here work done against friction is given so force of friction here is

F_f = 848 N

It moved by three corridors with each measures

d = 14.33 m

so total distance will be

s = 14.33 \times 3 = 43 m

now from above formula of work done we will say

W = 848 \times 43

W = 36464 J

so above is the work done to move three corridors

In a women's 100-m race, accelerating uniformly, laura takes 1.96 s and healan 3.11 s to attain their maximum speeds, which they
liubo4ka [24]
First we write the kinematic equations
 a
 v = a * t + vo
 r = (1/2) at ^ 2 + vo * t + ro
 We have then that:
 (10.4 - t) = time that they run at their maximum speed
 For Laura:
 d = (1/2) at ^ 2 + (at) (10.4 - t)
 100 m = (1/2) a (1.96) ^ 2 + [(1.96) a] (8.44)
 100 = 1.9208a + 16.5424a
 100 = 18.4632a
 a = 100 / 18.4632 = 5.42 m / s ^ 2
 For Healen:
 100 = (1/2) a (3.11) ^ 2 + [(3.11) a] (7.29)
 100 = 4.83605a + 22.6719a
 100 = 27.50795a
 a = 100 / 27.50795
 a = 3.64 m / s ^ 2
 Answer:
 the acceleration of each sprinter is
 Laura: 5.42 m / s ^ 2
 Healen 3.64 m / s ^ 2

A car moving with a velocity of 20 meters/second has 1.8 × 105 joules of kinetic energy. What is the mass of the car?
PSYCHO15rus [73]
V = 20 m/s 
Ecin = 1.8 x 10^5 J 

Ecin = m*v^2/ 2 
1.8*10^5 = m*400/2 
200m = 1.8*10^5 

I know you can do it :)
