Answer:
9m/s²
Explanation:
Given parameters:
Initial velocity = 30m/s
Final velocity = 0m/s
Distance traveled = 50m
Unknown:
Deceleration = ?
Solution:
To solve this problem, we apply the proper motion equation;
V² = U² + 2aS
V is the final velocity
U is the initial velocity
a is the acceleration
S is the distance
Insert the parameters and solve;
0² = 30² + 2(a)50
-900 = 100a
a = -9m/s²
The negative value indicates deceleration.
The motorcycle decelerates at a rate of 9m/s²
The direction would be dependent on the direction of the current through the circuit. But for this, you can use the right hand rule to determine the direction of the magnetic field. <span>The </span>right hand rule<span> states that: to determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the </span>right hand<span> in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.</span>
Answer:
a = 120 m/s²
Explanation:
We apply Newton's second law in the x direction:
∑Fₓ = m*a Formula (1)
Known data
Where:
∑Fₓ: Algebraic sum of forces in the x direction
F: Force in Newtons (N)
m: mass (kg)
a: acceleration of the block (m/s²)
F = 1200N
m = 10 kg
Problem development
We replace the known data in formula (1)
1200 = 10*a
a = 1200/10
a = 120 m/s²
Answer:
What happens when Chlorine reacts with Bromine
Explanation:
Both of them are electronegative and need 1 electron to achieve a fully filled electronic configuration.... When chlorine reacts with sodium bromide, we get a displacement reaction, in which chlorine will replace bromine. The balanced chemical reaction is: That is, we end up with sodium chloride and bromine.
