How far will a body move in 4 seconds if uniformly accelerated from rest at the rate of 2m/s square​

Physics
1 answer:
kirza4 [7]3 years ago
6 0

Answer:

16m

Explanation:

Given parameters:

Time  = 4s

Initial velocity  = 0m/s

Acceleration  = 2m/s²

Unknown:

How far will the body move  = ?

Solution:

To solve this problem, we use the expression below:

  s  = ut  + \frac{1}{2} at²  

s is the distance

u is the initial velocity

t is the time

a is the acceleration

 

   s  = (0 x 4) + ( \frac{1}{2} x 2 x 4²)  = 16m

In what way did the cloud model resemble the Bohr model
Ahat [919]

Answer:

While Bohr's atomic model hypothesizes that electrons move in particular energy levels around the nucleus, the electron cloud model suggests that electrons move in an unpredictable pattern but are more likely to be in certain regions than others.

17. In which layer does mantle convection occur?
Anarel [89]

Answer:

D. Asthenosphere

Explanation:

The asthenosphere is relatively plastic part of the mantle which underlies the brittle lithosphere. In the asthenosphere, it is generally believed that the rocks are in ductile state and easily moves. It is the site of convection within the earth. In mantle convection, hot and light materials rises and keeps moving into upper crustal levels till they solidify. Here also, cold and denser materials sinks deeper till they turn to melt. This differences in temperature and density sets up a convective cell within the mantle. Several convective cells are in the mantle.

Vector ~A has a magnitude of 29 units and points in the positive y-direction. When vector ~B is added to ~A, the resultant vecto
timurjin [86]

Answer:

The magnitude of vector B is 43 units and it points in the negative y-direction.

Explanation:

Resultant of vectors = vector sum of all the vectors

Vector A = 29j

Vector B = ?

Resultant of vector A and B = R = -14j

R = A + B

-14j = 29j + B

B = -14j - 29j = - 43j

Hence, the magnitude of vector B is 43 units and it points in the negative y-direction.
