The body of mass 1 kg is kept at rest. A constant force of 6.0 N acting on it the time taken by the body to move through a dista

HACTEHA [7]

Time taken by the body to move through a distance of 12 m is 2 s

Explanation:

using the equation for force

$F= m a$

m= mass= 1 kg

F= force= 6 N

a= acceleration=

6= 1 a

a= 6 m/s²

Now using the kinematic equation,

$d= Vt + \frac{1}{2} at^2$

d= distance= 12 m

V= initial velocity=0 as the object is at rest initially

12= 0(t)+ 1/2 (6) t²

t²=4

t= 2 s

Answer:

Following are the solution to the given question:

Explanation:

Please find the complete question in the attached file.

$a_x = 0\\\\a_y = -g = -9.81\ \ \frac{m}{s^2} \\\\v_{iy} = 0 \\\\y = v_{iy} \times t+ \frac{1}{2ay} \times t^2 \\\\ 15 = \frac{1}{2} \times 9.8 \times t^2 \\\\t = \sqrt{(2 \times \frac{15}{9.8})} \\\\$

$= 1.75 \ sec \\\\$

Distance:

$x = v_{ix} \times t \\\\$

$= 8 \times 1.75\\\\= 14 m$

A single particle of a compound is a

Sav [38]

Answer:

mixture

Explanation:

All matter is made of particles; these can be single atoms or atoms chemically joined to make molecules. Using this fact, matter can be classified into three broad groups: elements, compounds and mixtures. In an element, all the atoms are of the same type. If more than one type of atom is chemically joined, then a compound has been formed. If more than one type of atom or molecule is contained in the same substance, and the particles aren't chemically joined, this is a mixture.
