Answer:
31.06 deg
Explanation:
= speed of the stream = 0.633 m/s
= speed of the explorer = 0.739 m/s
= Angle with respect to shoreline
For the explorer to swim directly across the stream, necessary condition is

The coefficient of static friction is 0.357 and the coefficient of kinetic friction is 0.265.
Explanation:
Coefficient of static friction is defined as the proportionality constant for the frictional force between the crate and floor for starting the motion of crate and normal force acting on the crate. As the normal force of the crate is equal to the influence of acceleration due to gravity acting on the mass of the crate, the frictional force for static friction coefficient will be the force applied to move the crate.
Thus,
Since, the static friction force is 70 N, the normal force is equal to
So normal force is 196 N and static force is 70 N, and the ratio of static friction force to the normal force will give the coefficient of static friction.
Similarly, the coefficient of kinetic friction can be determined from the ratio of kinetic friction force to normal force. Here the kinetic friction force will be equal to the force applied on the crate to keep it moving.
Thus, the coefficient of static friction is 0.357 and the coefficient of kinetic friction is 0.265.
Answer:
Explanation:
Given
Digit: 1,500,000
Required
Represent using scientific notation
We start by expressing the given digit as a product of 1.5 and a multiple of 10
1,000,000 can be represented as 10⁶
So; the digit becomes
<em>Hence, the scientific notation of 1,500,000 is 1.5 * 10⁶</em>
