Opposite to gravity is the normal force. ... The normalforce<span> is always equal in magnitude and opposite in direction to gravity. An </span>object<span> may also have friction</span>acting<span> on it. Friction is a </span>force<span> that occurs when two</span>objects<span> rub against each other, restricting or preventing motion.</span>
In a frozen, solid state, the water molecules are arranged in a lattice and vibrate against each other.
When heat is applied to the ice, it provides energy for these water molecules. Thus, they begin to break from the fixed structure and can flow and move around each other, in a liquid state.
Answer:
6.0621 m/s
Explanation:
we all know that horizontal component of the velocity in projectile motion is
= u cosα
u= initial speed of 7.00 m/s of the gun.
α = angle of the initial velocity with the horizontal = 30°
therefore, horizontal component of the ball's initial velocity = 7×cos30°
The Y-component of the vector is 34.65 m.
<h3>What is a vector?</h3>
Vectors are quantities that have both magnitude and direction.
The Y-component of the vector can be calculated using the formula below.
Formula:
- Y = rsin∅............. Equation 1
Where:
- Y = Y-component of the vector
- r = magnitude of the vector
- ∅ = angle of the vector to the horizontal.
From the question,
Given:
Substitute these given values into equation 1
- Y = 82(sin25°)
- Y = 34.65 m
Hence, The Y-component of the vector is 34.65 m.
