Answer:
150 m
Explanation:
Given,
u=5m/s
a=2m/s2
t=10s
v=?
s=?
Now,
v=u+at
=5+2×10
=5+20
=25m/s
So,
s=u+v/2×t
=5+25/2×10
=30/2×10
=15×10
=150m
Two identical spheres (of equal mass) a distance of 10 meters apart exert a force of gravity of 0.00050 N on each other. What are their masses?
Answer:
The gravitational force between two objects is written as:
F = G*m1*m2/r^2
Where:
G = 6.67*10^(-11) m^3/kg*s
m1 and m2 are the masses of the objects.
r is the distance between the objects.
In this case, we know that:
F = 0.0005 N
r = 10m
and because the two spheres are identical, we have that:
m1 = m2 = M
then we have the equation:
0.0005 N = (6.67*10^(-11) m^3/kg*s)*(M^2/(10m)^2)
0.0005 N*(10m)^2/(6.67*10^(-11) m^3/kg*s) = M^2
√( 0.0005 N*(10m)^2/(6.67*10^(-11) m^3/kg*s) ) = M = 27,379.3 kg
The mass of each sphere is 27,379.3 kg

what is the process of subduction
Answer:
Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones.

Bicycle A with mass 40 Kg is traveling with a velocity of 4 m/s and Bicycle B with mass 20 Kg is traveling with a velocity of 2m/s. The two bicycles have kinetic energy
Calculate it and state which bicycle has higher energy and why?
Answer:
bicycle A has a greater K.E.
Explanation:
K.E = 1/2mv²
bicycle A = 1/2 × 40 × 4² = 320J
bicycle B = 1/2 × 20 × 2² = 100J
bicycle A has a greater K.E. because it has bigger mass and moves with faster velocity
3. What are the forces present on the rope?
Answer:
The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.
